Coherent Optical Image-Plane Correlator Study.
Abstract
-PERCEPTION. With stereo-photographs of a laboratory stereomodel, the correlator, successfully demonstrated its profiling capability by automatically clearing x and y parallax and correcting x-scale due to slope. With typical stereo aerial photography, inconsistent plotting performance was experienced. This result is attributed to the inadequacy of the simple control loops of the experimental correlator to cope with the spatially variant properties of aerial photography. While this problem could be overcome, it is recommended that subsequent effort be directed toward a different type of optical system which would make maximum use of the power of optical computing techniques while minimizing real-time adaptive control requirements. The approach considered is that of an epipolar coherent optical correlator which would perform parallel multichannel computation of one-dimensional correlation functions. (Author)
