Abstract

We describe a new optical system consisting of an active-matrix liquid-crystal television (AMLCTV) and a position-sensitive device (PSD) that tracks a moving object in television image in real time. The AMLCTV transforms the television signal into a two-dimensional optical image, and the PSD detects the center of the image projected onto the target without scanning. The advantage of this system is its ability to track accurately an object moving at a high speed.
