13. REQUIREMENT/AUTHORITY The 1032T Microdensitometer is limited in its ability to
(a) scan microscopic areas of imagery without producing extraneous data and (b)
analyze film imagery which exceeds 170 lines per millimeter in resolution.

16. END ITEM OR SERVICES FROM THIS CONTRACT/IMPROVEMENT OVER CURRENT SYSTEM, EQUIPMENT. ETC. The
Contractor will modify the Microdensitometer to: (a) Control the length of the scan
with digital switches and counters instead of microswitches, and. (b) change the
density sampling system from a mechanical base to a time base which will allow a
sampling rate of 10 samples per micrometer (versus the present rate of 1 sample per
17. SUPPORTING OR RELATED CONTRACTS (Agency & Other)/COORDINATION micrometer).
This contract will be run concurrently with a contract to modify a stage for the
1032T Microdensitometer. There is no overlap on these projects. Coordination has
been performed through EXRAND.
18. DESCRIPTION OF INTELLIGENCE REQUIREMENT AND DETAILED TECHNICAL DESCRIPTION OF PROJECT (Continue on addi-
tional page if required) The scan controller consisting of decade counters, switches
and comparison logic will replace the microswitch controls to allow the scan length
to be preset to from 1 micrometer to 1 decimeter. This precise programming of the
scan length will eliminate the extraneous data now produced on small scans and will
reduce costly processing of the data. The sampling system will be modified so that
it will be triggered by a crystal oscillator (the "clock") instead of directly by
the stage movement. The oscillator will allow better control of the sampling rate
and will permit more frequent sampling, thereby reducing the limitations to analyzi
