Abstract: A multiple target tracker and beam steerer utilizes a micro-electro-mechanical system (MEMS) micro-mirror array to illuminate multiple tracked targets per frame one target at a time for designation, range finding or active imaging. The steering rate and range afforded by the MEMS micro-mirror array supports various tracker configurations (out-of-band, in-band or dual-band video cameras), LADAR detectors (single pixel or pixelated) and prioritization of tracked targets to vary the revisit rate or dwell time for an illuminated target. A user interface accepts commands from an operator to select the targeting mode, control cue-box size and position within the FOV and target selection. The MEMS micro-mirror array may be used to reflect beams and/or optical signals, in some embodiments.

Abstract: A multiple target tracker and beam steerer utilizes liquid crystal waveguide (LCWG) beam steering to illuminate multiple tracked targets per frame one target at a time for designation, range finding or active imaging. The steering rate and range afforded by the LCWG supports various tracker configurations (out-of-band, in-band or dual-band video cameras), LADAR detectors (single pixel or pixelated) and prioritization of tracked targets to vary the revisit rate or dwell time for an illuminated target. A user interface accepts commands from an operator to select the targeting mode, control cue-box size and position within the FOV and target selection.

Abstract: An obstacle detector configured to identify negative obstacles in a vehicle's path responsive to steering a laser beam to scan high priority areas in the vehicle's path is provided. The high priority areas can be identified dynamically in response to the terrain, speed, and/or acceleration of the vehicle. In some examples, the high priority areas are identified based on a projected position of the vehicles tires. A scan path for the laser, scan rate, and/or a scan location can be dynamically generated to cover the high priority areas.
