A Technique for Obtaining Film Threshold Modulation.

Abstract

The Film Threshold Modulation is a measure of performance which can be combined with lens Modulation Transfer Function figures to give an assessment of lens/film performance. This Memorandum describes the techniques developed for obtaining the Film Threshold Modulation Curves for any type of film using a Resolution Camera. The results achieved for the two films tested are also presented.
