Micro-Mirror Optical Tracking and Ranging System

An innovative optical sensing and tracking system was designed to detect, track, and determine object distance and direction in a wide, full, solid angle (160 × 160°) with an extremely high spatial resolution (0.5°). A key design feature is the laser beam steering system comprised of micro-mirrors that spin and tilt synchronously to steer the beam across a predetermined scanning angle and interval in a conically shaped scan pattern.
