1. PROBLEM.
To extend the anamorphic magnification capability to the
a. Recently an anamorphic eyepiece attachment was developed'for
the Zoom 70 Microstereoscope. Operational evaluation
has shown that this attachment can be extremely valuable for stereo-
scopic fusion of certain oblique imagery. Production units of this
device were purchased and are in use in NPIC.
b. The High Power Stereoviewer is replacing the
standard Zoom 70 in certain phases of the photo interpretation operation,
especially in the detailed analysis phase.
c. Over 150 of the High Power Stereoviewers have either been delivered
or are on order.
3. DISCUSSION.
a. Current Procedure. The Zoom 70 has become the
standard microstereoscope for photo interpretation at NPIC. Because
of the inability of a photo interpreter to stereoscopically fuse conju-
gate images from geometrically distorted photography (e.g., high oblique
or convergent panoramic), the anamorphic eyepieces were developed to
overcome this deficiency in the Zoom 70. The High Power Stereoviewer
is finding increasing application in the photo interpretation operation
and the same deficiency exists in that instrument as was formerly present
in the Zoom 70.
b. Origin of Concept. The concept of employing anamorphic magni-
fication to permit stereoscopic fusion of certain operational materials
was first implemented by the Development Branch, P&DS in FY 1964. In
that effort a parallel development was undertaken to determine if the
principle of variable-ratio anamorphism would solve an otherwise im-
possible operational problem. The program for the Zoom 70 was successful
and a number of production units were purchased. These instruments were
somewhat awkward'to use; consequently, another effort to develop an
instrument designed for the highest degree of operator comfort commensurate
with the required performance characteristics,is underway.

1e c. Proposed Program. This project will result in the design and
fabrication of a set of prototype anamorphic eyepieces for the High-Power
Stereoviewer. The program will be divided into two phases: Phase I
will be the Design Study and Phase II will be the Fabrication Phase.
Initiation of Phase II will be predicated upon the successful completion
of the Phase I design study.
d. Technical Characteristics.
1) Anamorphic Range. The system will have a continuously
variable anamorphic magnification from 1X to 2.2X; i.e., the
anamorphic ratio (ratio of the magnification of two perpendicular
meridians of the optical field) will be from 1:1 to 1:2.2.
2) Field. The maximum loss of field will not exceed 5% of the
normal instrument's total field without the anamorphics. No
significant field curvature will be introduced by the anamorphic
system.
3) Anamorphic Axis Orientation. The direction of the anamorphic
magnification (anamorphic axis) will be rotatable through 3600.
k) Physical Configuration. The eyepoint will be extended
approximately three inches from the position of the present eyepoint
and an operator wearing glasses will be able to operate the in-
strument.
5) Interchangeability. The system is configured to allow
disassembly of the anamorphic system from the stereoviewer within
three minutes without the use of special tools. Accommodation is
made for utilizing the system on any High Power
Stereo

6) The anamorphic system will not significantly degrade'the
optical performance of the High Power Stereoviewer equipped with the
Wild Fluotar objectives and compensating eyepieces.
e. Selection of Contractor. I Isubmitted their
proposal in response to the Development Objectives entitled:"Advanced
Anamorphic Eyepieces" dated 2 August 1966. Of the seven companies
invited to bid only three responded. I Iwas chosen because:
(1) their proposal was the best technical response to the objectives,
(2) of their experience in the field of development of anamorphic
eyepieces (they were awarded the contract by this office for development
of the advanced anamorphic eyepiece attachment for the Zoom 70), (3) they
developed the High Power Stereoviewer and therefore are more knowledgeable
of the characteristics of this instrument than the other bidders, and
(k) they were the lowest bidder.
f. Program Phasing. This project will be a two phase effort.
Specifically, the design phase will require four months and the
fabrication phase five months and will be predicated on the successful
completion of the design study.

g. Coordination. There is no known equipment either under develop-
ment or available commercially which will satisfy this requirement. This
has been coordinated with DDS&T/ORD, disseminated to the intelligence
community through the 1966 NPIC Equipment Summary and presented to the
Committee on Photographic Exploitation. Specifically, representatives
of the Naval Air Systems Command, Rome Air Development Center, and the
Geodesy, Intelligence Mapping Research and Development Agency maintain
that no effort within their responsibility duplicates this project.
A previous contract at NPIC has resulted in successful anamorphic eye-
pieces for thel Model II Stereomicroscope; however, no
anamorphic eyepieces for the Twin Dynazoom Microstereoscope (150 of
which are on order) exist or are in development.
h. Alternatives. The only alternative to this program would
be to continue to operate the High Power Stereoviewers in the present
manner without the ability to fuse certain stereoscopic imagery.
4. CONCLUSIONS.
The Advanced Anamorphic Eyepieces promises t be significant
improvement in the utilization of the High Power
Stereoviewer. Since it is presently impossible to view certain imagery
with adequate stereoscopic fusion, this attachment must be developed.
5. RECOMMENDATIONS.
Tt LS, recommended that approval be granted to contract with
