This phase will be com- pleted in a period not in excess of six (6) weeks from date of contract. b. Design and Manufacture - Phase II This phase will consist of the design and manufacture of an instrument either Gamma I or II as defined herein in accordance with the design speci- fications resulting from the Design Plan phase as approved. If the evaluation and acceptance of the Design Plan. is completed in a period of three weeks from day of submittal, the project will be completed nine (9) months from the date of contract. Phase I TAT 0 will consider rectification of two general catagories of tilted panoramic photography and all investigation in studies performed under this phase. These two catagories of photography, designated Gamma I and Gamma II photography respectively, have the following characteristics.

TECHNICAL CONSIDERATIONS The technical considerations discussed in the following para- graphs delineate the general parameters which influence or control the design of the proposed rectifying printer, and include factual descriptions of those designs, components, and techniques utilized 9005 and 8075 which will be included in the proposed DESIGN CONSIDERATIONS Assume that a vehicle using a panoramic sweep camera is flown over a rectangular pattern on the ground with no compensation made for "image motion" due to vehicle velocity and altitude.. As the rectangular pattern on the ground is recorded on the film, the pattern image is distorted. The distorted pattern reflects the change in X and Y scale as the scan approaches the horizon in addition to the scale changes resulting from tipped photography. The most effective means of removing the distortions is to reinstate the basic camera motions and geometry in the transforming projection printer so that the original photography, with its inherent distortions, will be photographically transformed into a central projection, which is near a vertical photograph of the ground. The basic geometrical concepts of tipped sweep photography are followed throughout transforming printer optics. However, the instrument must deal with finite imago and object distances, a requirement which imposes the. following three conditionst 1. The lens system must remain centered at the center of projection in order to maintain the proper ratio of Approved For Release 2003/05/152 1IA-RDP7W00L$JOZ8 Approved For Rq@JP Wb1 Vftfwd 200010032-8 is longitudinal and transverse scale. 2. An axial element at any position must remain focused at the corresponding position in the projection plane during the scanning process. This is accomplished by scanning the optical axis of the projection lens as a function of the actual scan angle thus ubing the field of the lens to obtain the image and conjugate distances required to fulfill the Newtonian equation. 3. In order to focus a complete line, such as that formed primarily by the projection of a slit length on the easel, and secondly by the slit width itself, the Soheimpflug condition must be fulfilled. With a tipped oblique photograph, the negative plane and the ground plane (the easel plane in the printer) must intersect. If the plane of the lens is rotated about the projection center of the lens until it too passes through the intersection of the negative and easel planes, the Scheimpflug condition is fulfilled and a sharp image of the negative is projected onto the easel. Because the easel plane on the proposed instruments is curved to approximate the earth's curvature in scale and because the easel tip angle is variable over a range of from 10-200, no finite value naay be assigned to the 0 Saheimpflug lens angle, instead it must be an infinitely varying quantity over some unknown range to compensate for an infinite number of tip angles and positions on curved easel conditions. In addition, the use of two easel configurations places further variable conditions 2-2 Approved For Release 2003/05/15: CI CI O EIPM010032-8 Approved For Rc*'S 5/1 441AU 78B04747A 200010032-8 on the Scheimpflug angle requirements. The solution to this problem requires a fairly substantial amount of computer programming. We propose to perform this task during the Design Plan phase of the contract. Operationally, both films will remain fixed in position during exposure while the processed film is being scanned by a slit mounted integrally with a projection lamp, diffuser, and condenser lens on an exposure arm. The light will be diffused and projected through the slit and focused at the nodal point of the projection lens. After the image leaves the projection lens it will be reflected from a front surface mirror onto the copy film easel. Scalar dis- tortions introduced by the tipped panoramic photography will be transformed during the reproduction operation; therefore, it will be possible to measure scalar distance directly on the copy film with- out resorting to scale corrections. The transformation will be 0 TAT 0 TABLE OF COMPONENTS The printer will consist of the fallowing general compbnent sections: a. Main Assembly b. Processed Film Transport System c.

In addition, a desk type safelight embodying an integral "ON-OFF" switch will be provided for the operator's convenience. A convenience outlet wired for 115 volts A.C. will be mounted on the base plate for the eafelight connection. This outlet will be "live" when the instrument is connected tr.-, ther line power and will be unaffected by the main power switch. Processed Film Transport System The film transport system will be a simplified manual system and will consist of'the supply and take-up spindles, two idler rollers, a tension roller, a drag brake on the supply spindle and a hand crank on the take-up and supply spindle. In addition to the above it will include a curved film platen designed to duplicate the relative position and curvature of the Panoramic Sweep Camera. Copy (9-inch) Film Transport System The 9-inch film transport will be similar to the processed film transport with the following exceptions: 1. Instead of the film plater a combination easel will be provided. The easel will have trunnions at the ends of its long axis and have two faces. One face will be shaped to a 91' radius curvature; the other will have a 127' radius. It will be possible to rotate the easel to select either of the two anticipated simulated earth curvatures. 2. The curved easel surfaces will be provided with vacuum grooves to hold the film flat. Each of the two easel faces will Appvveed A? F9e easec/~? G~fbs78 to a common vacuum pump and e il'LUPL XxPoULIX Approved For R /1HAN Sl8B04747AIM200010032-8 49 ? accumulator. Solenoid valves and switches will be provided so that the vacuum system of the face in use may be activated while the other remains inoperative. 3. The 9-inch film transport system will incorporate a means for metering out the length of copy film required to print the complete format of the negative image. This device will be designed so as to maintain the spacing between copy frames at the minimum distance consistent with prevention of overlapping copy exposures. 4. The take-up spool will be enclosed in a light tight cassette. Mop Mechanic System The sweep system embodies a projection lamp housing, an exposure arm, and a variable speed am drive. The image distance varies from minimum at thb nadir point to maximum at either end of the easel. This causes a light fall-off that increases from the nadir to either end of the easel. This inherent light fall-off is compensated for by varying the angular velocity of the exposure arm and the projection lamp voltage. Two variables are introduced by the driving mechanism to achieve a velocity curve which partially compensates for the light fall-off curve. The arm is driven through its sweep by means of a friction wheel located to give a peripheral drive motion to the arm. A drive motor is connected to the friction wheel in such a manner as to convert rotation to translation. The translation is transmitted.to the arm through a sliding linkage which imparts angular velocity to the arm. Because of the sliding linkage, the translation force is applied tangentially at constantly varying arm radii, thus varying the a m's angular velocity so that velocity is minimum at the ends of the sweep and maximum at the nadir position. In addition to the velocity variation induced by the sliding linkage mechanism, another variable is induced by varying the projection lamp voltage. The drive mechanism is coupled mechanically to a variable transformer which is Approved For Release 2003/05/15 : 2Cj.A-RDP7JQtU&O J fA?&JQ,32-8 Approved For R lif ~51 PI~'N13P78B04747 200010032-8 connected to the projection lamp in such a manner that the position of the arm determines the voltage. Voltage (and consequently light intensity) is maximum at the beginning of the sweep and decreases to min' at the nadir point,, Here the transformer references is changed by automatic switching so that the voltage increases to maximum at the end of the sweep. The arm sweeps approximately plus overtravel at each end. The overtravol allows a predetermined acceleration and deceleration rate before and after the exposure cycle to reduce mechanical transient vibration. 0 0 2?6 Approved For Release 2003/05/15 91 M78f J P 00010032-8 ? 0 Approved For R*s / /15 : CIA-RDP78BO4747*200010032-8 AUTOMATIC EXPOSURE DETERMINATION The exposure control parameters are defined by the requirement to print negatives of varying density to a standard uniform density. Itek has utilized this technique in previous printing instruments, including the Signal Corps EN 71 Rectifying Projector Printer. The actual control will be accomplished by varying the pro- jection light intensity, the scan velocity, or by a combination of both of these procedures. The mechanics of the control system will be developed so that the setting of a single dial type control will adjust the light and/or velocity to the level required to print the copy. A prerequisite for this system is to establish the manner in which control setting information is to be derived. Any particular negative frame may be essentially homogeneous in density or may have a number of areas of different densities. With an homogeneous density negative, the exposure control technique is simply to print it out to the standard density. Negatives with areas of varied density, however, offer the possibility of two techniques: 1.) A representative number of different density areas may be evaluated and these results intergrated to an average negative density. The exposure control may then be set to the average and the printed copy will be printed to an average standard density (if evaluated in the same manner). 2.) A significant area may be selected and evaluated. The exposure control may then be set to the value of the selected area. 2-7 Approved For Release 2003/05/15 : VT&kB}flMG)0010032-8 Approved For Rose EtIN 5 h~lA S B04747A0200010032-8 ? The selected significant area of the copy will be printed to the standard density with the remaining area densities varying relatively as on the negative. Our approach to the method of film evaluation and exposure control setting is governed by the overall philosophy of simplicity and economy. Exotic automatic systems which represent costly and time consuming design and fabrication or involve sophisticated operator techniques have been precluded from consideration. For the density evaluation operation, we will provide a combination inspection station-light source,positioned to illuminate the frame following the one positioned in the projection platen. The light box will contain fluorescent or incandescent lights arranged to shine through an opal or frosted glass plate. The glass plate will be the same size as the frame format and will be located so'that the film lies on it with the backing side in contact with the glass. A Densichron Photometer or equivilent with a Blue Meter probe will be provided and the probe will be mounted or stored so that the operator may place it over any portion of the film frame. The Densichron unit will be connected to a log scale exposure meter which will be mounted in an area where the operator may read it conveniently while he is probing the negative. The exposure meter will be calibrated so that its scale reading represents the negative density. Inclusion of the viewing-evaluating station will increase instru- ment length about ten to twelve inches. For the exposure control setting operation, a dial type exposure control will be provided, this will be calibrated so that when the exposure meter reading is set on the exposure control, the light Approved For Release 2003/05/15 : RDP7LJ00 lWP_8 SPECIAL HANDLING Approved For Rose 2003/05/15: CIA-RDP78B04747P 200010032-8 18 0 intensity and/or scan speed will be adjusted to print a 0.6 density from a negative of the selected density setting. In addition, a dummy exposure control identical to the actual exposure control will be mounted adjacent to the actual. This will be utilized to record the evaluated density and to retain the information until the operator is ready to make the setting. ,z.9.

The image will be folded, after it passes through the projector lens, by means of the front surface mirror. The folding operation will serve to accommodate the long optical path in a minimum of space.

PROPOSAL DIGEST INTRODUCTION is pleased to submit the following proposal for the design and manufacture of a transforming projection printer, des- ignated Gamma I. in quantities of one (1) and two (2) unite. We propose that the task be performed in two separate phases: a. Design Plan - Phase I This phase will consist of the thor- ough investigation and description of design approaches, and the analysis and solution of all the presently indeterminate optical parameters and problems. It is anticipated that this phase will be completed in a period not in excess of six (6) weeks. b. Design and manufacture ? Phase II This phase will consist of the design and manufacture of the Gamma I instrument/s in ac- cordance with the design opecifications resulting from the Design Plan phase. The separation of preliminary engineering and scientific investi- gations from the design and manufacturing phase, and the incorporation of the investigation results into a Design Plan, will insure (especially in the absence of detailed specifications) a "meeting of the mincs?' be- tween contractor and customer prior to the initiation of actual fabrica- tion, and thus preclude misunderstandings during the performance period. In line with this philosophy, it is desirable that the customer sh ,l evaluate the Design Plan and define all exceptions and objections prior to acceptance. If the evaluation and acceptance of the Design Plan is completed 1-1 Approved For Release 2003/05/15 :k86 200010032-8 Approved For Release 2003/05/15 : CIA-RDP B04747AO03200010032-8 .0 SPECIAL HA DUd H ! 0 in a period of three. weeks from day of submittal, we feel that the project can be completed nine (9) months from the date of contract.

These items will be considered in detail in the Design Plan. Items (c) Exposure control and (d) Earth curvature are included in the technical section of this proposal. DESIGN OF THE GAMMA I PRINTER The operating parameters of the Gamma I instrument are similar to those 9005 Indexing Rectifiers which were completed in 1960 and are presently operational, proposes to utilize existing designs and mechanisms to the great- eat extent possible. There are two significant differences in operating parameters between theeGamma I and 9005 instruments which will require design changes of Approved For Release 2003/05/1 : rn"M ? Approved For R.se 2 I" ME 9A. WW 04747A,200010032-8 appreciable scope. The first difference is the requirement to increase the Gamma I magni- fioation to approximately 1.875X as opposed to 1.4X for the 9005 instrument. Three design changes are necessary to meet this demand, they are: a. The change in magnification necessitates the use of a lens different from that used in the 9005 machines. Inquiry has disclosed that there are no lenses commercially available which will meet the re- quired specifications; therefore, two courses of action are avail- able: First, the lens can be scaled up by the 25X1 manufacturer to the specific requirement for a 400.-mm f/9 lens. This lens has the advantage of being quite reasonably priced; but, the resolution capability is low, i.e. it approaches 50 1/mm. Due to the requirements of the Gamma I system, this lens will not be oondiderod initially. Second, has the preliminary designs for, and will con- struct a lens of suitable focal length and field angle. The lens resolution capability will approach 80 1/mm. At present we will consider the construction of this lens as the optimum choice of action. The forecast completion date of the comfortably within the proposed development period, b. The change in magnification increases the size of the copy format. To adapt for this change, we will re-design the copy film transport system to increase the easel dimensions to accommodate 9-inch copy film. Concurrent with the design change to adapt for the larger copy film, we will also simplify both the negative and copy film transports to manually operated systems rather than the powered automatic systems of the 9005 instruments. 1?4 Approved For Release 2003/05/15 !Sl 163200010032-8 STA STA ? 0 Approved For R se 219 U~8%04747AJ#200010032-8 o. The increase in magnification also requires an increase in the length of the optical path. The configuration and dimensions of the optical path components will be revised to fulfill this re- quirement. The second difference in operating parameters is the requirement that the Gamma I instrument have the capability to transform tipped photography distortion. Whereas the 9005 instrument had the easel mounted in the vertical position and fixed in place, the Gamma I easel will be tipped to a nominal tip angle (4' ) of 150 with means provided to vary this angle 1 50. The easel will be curved to simulate earth curvature, subsequent evaluation will disclose whether a fixed curvature or two distinct curvatures are required. Should the two shapes be required, we will design either an adjustable face easel or an indexing easel with two film faces. In addition to the above, it is necessary to tip the Ions in order to fulfill the Soheimpflug condition. We will tip the lens approximately 6 at the nadir position and design the focusing cam mechanism so that the Scheimpflug condition is fulfilled at cell points of the sweep for all easel tip angles and for the two easel configurations if these are shown to be required. Details of the proposed designs and re-designs are included in Section II of this proposal. It is to be understood that all technical statements contained in this proposal are somewhat flexible and are subject to changes occurring from the results of the Design Plan phase. The accuracy statement is contained in Addendum I to the proposal. Approved For Release 2003/0!1+?: C J0010032-8 Approved For 0 seL M a 04747A 200010032-8 II.

The magnification is fixed and the lens focusing is cam corrected. The geometric errors in the transformed print due to the combined image motion and image motion compensation are rigidly predictable if the V/H factors and the I.M.C. camera constants are known. The geometric errors in the trans- formed print due to an approximate earth curvature correction is rigidly predictable provided that the true curvature for a certain flying height and tip angle can be determined. Earth curvature correction and the errors are being studied in more detail as a full compensation for this error results in complex optical and mechanical solutions. The proposed projection lens is to be Orelativ my distortion freoo' ac- cording to the designer, although high resolution and email distortion is not as optically compatible as one would like. Pre joctod lens distortion occurs only in the length of the scanning slit and therefore is not ac criti- cal as the mechanical scan as far as the major phetographic deformations are concerned, Film flatness is a problem faced in panoramic emneras as well as trans forming printers based on this reprojoction principle, Hecauso of this wee have had consider able experience in scan and film po yltioning components. The problem is con drably logs in the printers as the scan spend is much slower. Film flatncGs is of great geometric importance when using large optical field angles. For instance a vertical deviation of the film plane where the lens is being used at a field angle of 450 is relfosted by an equal magni- tude error in image shift. In the scanning printer the lens angle is defined in one direction by the slit width and film unflatness is negligible. In the other direction the lens is being used at a noderate angle due to the A >> Approved For Release 2003/05/15 : CI B0, A0032Q0010032-8 Approved For R JUP78BO4747AS200010032-8 optical condit'lone but the total angular field only novl-oru the 70-mm film width o No error otudies of the egieting printers have 'con made a ila la and final photograrametric assuracy ran only be predi? tod using available dnta?
