Dynamic Color Scanner System
Abstract
A three-aperture image dissector television tube is employed in a three-color photographic film densitometer. Equipment was assembled to accept reel film up to 9 inches in width, measure density, accumulate measurements and generate histograms describing the film density distribution. Sample size at the film plane is 94 microns with the number of samples per histogram variable to 1, 000,000. Each sample is classified as a density between 0.3 to 3.0 in 0.1 density increments. Histogram outputs are on oscillograph, paper tape and magnetic tape. Program details were reported in monthly and this final report as well as an equipment manual.
