DESIGN AND DEVELOPMENT OF A MULTI-DETECTING 2-DIMENSIONAL RANGING SENSOR

The development of a new, robust and compact system capable of acquiri ng two-dimensional range information of a target object within an imag e scene at near video frame rates is described. The system is based up on the high-speed gating capability of laser diode illumination, and a micro-channel-based image-intensified CCD camera. The technique diffe rs significantly from conventional time-of-flight-range gated systems, since the range information is determined purely by measurement of th e relative phase and intensity of a reflected light pulse.
