Some Design Considerations for Digital Position and Velocity Detecting Systems

Design-type information is presented for a system that uses pattern recognition principles to sense position and velocity of moving objects. Judging from the literature, little or no work has been done on this type of system. It is believed that these systems have potential industrial and military applications, e.g., an optical object finder that identifies objects in addition to locating them, or a process control sensor to detect grain size and other dimensional properties. One of the most important parts of the system is the receptor. Minimum receptor matrix size as a function of pattern shapes, orientation, position, and velocity is considered and results are presented.
