Abstract : A study is presented of image evaluation for reconnaissance photography. Among the objectives are: (1) to assess the possible advantages of new concepts such as modulation transfer function, and how far they can replace resolving power for system evaluation and specification; (2) to examine questions of accuracy and convenience concerning the new measurement techniques; and (3) to establish criteria for the detection of targets of specific shape and contrast. Research included preparation for laboratory simulation of aerial photography, including a study of the problems of realistic simulation by transparencies; simulated photography with various transfer functions; studies in system analysis; initial measurements of lens transfer functions; and emulsion threshold modulations.
