Abstract:
Divisions of the work described include a precision camera and associated equipment for simulated aerial photography, further work on emulsion threshold modulations and their use in predicting system resolving power, a study of the possibilities of interferometer techniques for exposing sinusoidal patterns onto emulsions at frequencies up to 750 lines per millimeter, and experimentation with coherent light techniques for exposing sinusoidal patterns onto emulsions and analyzing the exposed patterns. The modulation transfer function of Kodak Tri-X film has been determined by the coherent light method out to 110 lines per millimeter. The results agree with the published figures, within a few percent, above 20 lines per millimeter. Author
