The work described in this report is the continuation of the development of an automatic stereo compilation system based on coherent optical techniques. A breadboard coherent optical mapping system was modified to improve its accuracy and overall performance while at the same time simplifying the basic optics involved. Methods for preprocessing imagery to enhance correlation performance were studied and phase-type spatial filters were used to increase optical efficiency. The problem of data readout was investigated with particular attention to the use of an optical heterodyne technique. Computer and interface requirements for a fully automatic breadboard system were established and the use of real time filters was considered. Results indicate that this coherent optical system has considerable promise in the area of parallax measurement and, with slight modification, may be a useful tool for feature extraction from aerial photographs.
