1,5 The High Precision Stereo Viewer (Figure 1) was developed as an
#amprcved version of the High P agnification Stereo Viewer (NAVPIC report
203/6:3-i1) developed for the Navy and delivered to the Center in late
1962.
1.7 The prototype instrument, designated model No. 387 by the msnu-
fa`+cturar, was highly successful in its own right as a stereo viewer.
By the ti> it was c,pleted, however, many improvements such as
mensuration as +~a11 as greater optical and scanning versatility had
bocce fenoible through recent. advancemnts in electromopticaal
teehnoloy.
1.8 The subject instrument, designated model No. 552A-101, Serial No.
103, was developed from Proposal No. 552A of
July 1963 for as improved version of the model 387 viewer.

with couremeni: capability. Film transparencies in roll or chip form
and of diffaront:ial scales and orientations may be scanned and nsured
in stereo over dual 9 x 18 inch formats. The optical system provides
wide ver?satilit,y available at the eyepiece aseembly (Figure 2) along
with inde ndently variable zoom gnification of 1.6 to 128 ti aa.

6. CONCLUSIONS
6.1 The High Precision Stereo Viewer is entirely useful in its present
fc. m for ?evy photographic interpretation use,
6.2 This viewer offers goorl optical c,ualit~, and versatility for use in
detailed photo interpzetaation. The hJgt, resolution stereo viewing
versatility and, measuring capabilities of hio unit could make it a key
inotru nt th helping to mike the ta.ansitxr2n from present hand methodo
to c ?uterizeei real time photo inter-pre tril: ion.
7.1 It is recorended that the viewer be used operationally within the
4cand for. detailed photo interpretation.
7.2 It is ream nded that the Center continue to investigate possible
it preset nto in the viewer itself as well as mensuration techniques
and pro3rat .o to widen they utility and application of the inourt=ant.
