Monthly reports, final report, operating manual, production model viewer.
Better uniformity in intensity of image (improved grating), larger exit
pupil, improved controls, possible stereo capability.
17. SUPPORTING OR RELATED CONTRACTS (Agency & Other)/COORDINATION
The Agency has sponsored the development of a preliminary, prototype direct
image viewer, to be delivered by February 1966. Contacts throughout industry and
Government have revealed no concurrent or previous similar developments.
18. DESCRIPTION OF INTELLIGENCE REQUIREMENT AND DETAILED TECHNICAL DESCRIPTION OF PROJECT (Continue on addi-
tional page if required)
The Direct (Virtual) Image Viewer employs a unique approach to high
resolution rear-projection viewing of photographic films. Diffraction gratings
and a large field lens are used to provide an observer with an enlarged aerial
image which can be viewed simultaneously with both eyes without the use of a
screen.

18. The various characteristics of this viewer are listed below.
1) Magnification - dual magnifications of 5X and 50X.
2) Observable Film Area the observable film area consists of
a two (2) inch by two (2) inch square area in the film plane at 5X
magnification, and two-tenths inch by two-tenths inch 'square area in
the film plane at 50X magnification.
3) Film Size - the viewer accepts for viewing single frames of
-either 4 x 5 inch or 70mm x 100mm film chips.
4) Exit Pupil Size - the size of the composite exit pupil is
at least 3.5 inches square;
5) System Resolution - at 5X magnification, the viewer is
capable of providing a system AWAR resolution of 20 lines per millimeter
over. the used field when referred to a low contrast target in the
object plane. At 50X magnification, the viewer is capable of providing
an on-axis resolution of 200 lines per millimeter at the film plane-
with a low contrast target.
6) Light Intensity - the illumination system is variable: and
presents to the eye, with an open film gate, that amount of light
flux as presented to the eye by a lambertian source with illuminance
of 100 ft-lamberts.
7) Illumination Spectrum - the illumination of the viewer
system is contained in a narrow portion of the spectrum centered
around 508.6 millimicrons. Various filters may be used to provide
different band passes.
8) Film Positioning - the viewer incorporates a provision for
remote film positioning through X and Y translations to permit full
coverage viewing areas for either 70mm or 5 inch film chips.
9)' Focusing - manual fine focusing control is provided for
each magnification.
10) Film Temperature - the temperature of film when mounted in
the film plane of the viewer during operation does not exceed 90?F
with an average density (silver) of 0.8.
11) Viewer Controls - the control panel contains the following:
a) main power - ON/OFF
b) lamp ON/OFF
c) illumination intensity control
