Abstract
A laser ranging system based on agile galvanometric scanning has been developed for helicopter obstacle avoidance applications. Eye safety and fast repetition rates requirements were fulfilled using Q-switched erbium doped-fiber laser technology. In order to produce a maximum scan field of 20°×30° at a frame rate of 1.3 Hz with 10% fill factor, four lasers were combined. Field trials have demonstrated the detection performance of the system, capable of producing fused LIDAR and video images of high tension wires in clear weather conditions at 400 meters.
