PROJECT INSPECTOR
Progress Report for November 1964
1. PROGRESS OF WORK
Through calculations and experimentation the practicability
and limitations of the various methods for implementing the
enhancement system were determined. Two basic methods were
selected as the most feasible and the most likely to achieve the
design requirements.
One method will back-light the photo with a modulated Cathode-
ray tube, using a broad, defocussed beam. Viewing will preferably
be done by means of a vidicon and monitor. For direct viewing a
memory device will be used. A possibility of direct viewing without
the memory, and of coupling that with a "spotlight effect" is also
being tried.
The second method calls for simultaneous scanning of the photo
with a broad spot of light and with a very fine spot. This is
accomplished with a single cathode-ray tube and suitable lenses and
mirrors. The pickup device for this method is a photomultiplier
and the viewing is accomplished by means of suitable monitors.
The basic elements for both these systems have been proven
feasible. An effort is now being made to assemble small scale sample
systems with materials that are available on short order.
To date, the use of vidicons and closed circuit television
techniques appear to offer the best solution to the problems of low
light levels? proper back-lighting control, magnification and X-ray
hazards. The resolution capability, at the film plane, of a television

viewing system is limited essentially by the illumination available.
It presently appears that with proper techniques and state-of-the-art
components, it will be feasible to attain the required resolution.
A 1000- or 2000-line television system, properly interlaced and viewed
from, the proper distance, can match the resolution capability of the
human eye and show no scan lines. Magnification and traversing can
be done by remote control with no danger of damage to the film and
the convenience of viewing the magnified image without squinting through
a magnifier. An additional advantage of the system is the possibility
for a number of people to view the same magnified area simultaneously,
even in different locations. Photos could also be taken immediately of
the magnified and enhanced view for comparison or future reference.
A trip was made to observe the photo interpretation methods
used at Westover Air Force Base. Arrangements are being made to
visit the Naval P. I. Laboratory in Washington, D. C. and some
tactical P. I. installation. We feel that it is necessary to be familiar
with existing practices in order to suggest new methods and/or devices.
2. PROBLEM AREAS ENCOUNTERED
Assembling a sample system to illustrate the true capabilities
attainable will probably be impossible due to the cost and required
lead time for the required components.
3. PROJECTED WORK FOR THE NEXT PERIOD
Assemble a sample system which will illustrate the suggested
devices and provide a basis for extrapolation of the eventual
capability.
Execute the planned field trips.
