In this paper we present an IC array of photosensor and analog signal processor cells that acquires 1000 frames of light-stripe range data per second--two orders of magnitude faster than conven- tional light-stripe range-finding methods. The highly parallel range. finding algorithm employed requires that the output of each photosensor site be continuously monitored. Integration of processing at the point of sensing makes implementation of this algorithm practical. Prototype high-speed range-finding systems have been built using a 5 x 5 array and a 28 x 32 array of these sensing elements.
