ABSTRACT:
An optical pattern follower uses a photo matrix to scan a pattern. The scan pattern is determined by generating a series of point addresses storing such addresses and interrogating the matrix only when the point address in the matrix being scanned corresponds to an address in the store. The resulting signals are processed to produce direction velocity signals which cause the follower to follow the pattern at a predetermined tangential velocity.
