VERTICAL BEAM STEERING WITH A MEMS PHASED-ARRAY FOR LIDAR APPLICATIONS

A light detection and ranging (LIDAR) system incorporates a scanning system with random access pointing. The scanning system has a light source that generates a coherent light, a micro-electro-mechanical system (MEMS) phased-array that steers the coherent light in a vertical direction, and a resonan...

Zusammenfassung:	A light detection and ranging (LIDAR) system incorporates a scanning system with random access pointing. The scanning system has a light source that generates a coherent light, a micro-electro-mechanical system (MEMS) phased-array that steers the coherent light in a vertical direction, and a resonant scanner that scans the coherent light in a horizontal direction. The coherent light is projected onto a far field scene. The MEMS phased-array steers the coherent light to point the projected light on selected spots on the far field scene in random access fashion.
