LASER DISTANCE SENSORS CAN BE USED AS LASER ALTIMETERS
THE AR3000 HAS BEEN USED BY NASA AND UAV MANUFACTURERS TO CREATE LASER ALTIMETERS
Un-manned Autonomous Vehicle (UAV) projects depend on sensors to provide spatial information for route planning and crash avoidance. A developer of an un-manned airplanes selected AR3000 distance sensors to measure the height above the ground, whether it was the landing strip, grass or trees. A dual-sensor system can be used to give improved accuracy at both short range and long range distances. A 10 mrad version can be used for measuring between 0 – 50 meters, and a 2 mrad version can be used for 50 – 300 meters. NASA has also used Acuity’s products to create laser altimeters for their landers.
