Paper Abstract

A spatial light modulator can be used to actively illuminate moving objects with spot patterns. This research studies the spot patterns designed to detect and track object motion. To enhance the detection and tracking process, a system supervisor dynamically updates each successive spot pattern. The spot patterns are implemented by pseudo-randomly encoding their frequency plane into a phase-only filter to be implemented on a 128 X 128 Boulder Nonlinear System's LCD device. The modification of the spot patterns are based on the change of reflected intensity from one frame to the next. Detection, tracking, encoding and supervisor design and methodology are presented.
