Monthly Narrative Report P June 1966
A. Current Status of Work
1. Final Report Preparation
Drafts of all sections of the final report have been prepared.
These drafts are now being reviewed, and modifications will be made as
required. Copies of transparencies and figures required for the report
are also being prepared. Editing and final preparation of the report
for publication will take place this month.
2. Electrical=Chemical Processing
Final processing was completed on two frames, No. 1.6972 and
No. 16890 from the AFSPPL film. The former contained light struck areas
while the latter contained both clouds and haze over some portions of
the ground scene, Several combinations of modulation level, exposure
time, and intensity were tried for each of these pictures using the modu-
lated light contact printer. One set of values proved best for both
modulation and intensity, but exposure time variations had different
effects on different parts of the picture. Processing included generation
of positive copies of the scene to compare with the original as well as
sample step tablets generated under the same printer conditions as the
scene to compare desnity level changes. The behavior of the step tablets
under modulated processing was examined to determine some of the character-
istics this type of processing and to help determine the parameters for
scene processing.

3. Electronic Processing
The government9a technical representative informed ]n June 6, 1966 STAT
that the replacement high resolution CRT?s should not be purchased under the
contract for the electronic processor. Consequently, no further experimentation
was performed on this subtask during the month. A meeting was held with the
government9a technical and contracting representatives on June 15, 1966 to
discuss the final report write=up on this subtask in the light of the curtail-
ment of experiments. It was agreed that the write-up should include a description
of the system and the major hardware modifications made since its initial design,
a discussion of the problems encountered (with all equipment developed on the
contract), a description of the experiments that were to have been performed, and
what information was hoped to be obtained from them.
14. Techniques Analysis
The analysis of the effects of modulated light processing on density step
tablets was continued. Mathematically, some of the results demonstrated with the
CRT printer were simulated, in particular, the leveling-off and the triangular
shape of steps at high densities as shown in microdensitometer traces. Final
work was also completed on the comparative use of the simple processor and the
contact printer mathematical models for analysis of modulated light processing.
B. Projected Work for Next Month
Complete final drafts of the final program technical report, edit, and prepare
the report for publication.
