Abstract

An optical scanner including micro-electromechanical system phased-arrays suitable for use in a LiDAR system, and methods of operating the same are described. Generally, the scanner includes an optical transmitter having first phased-arrays to receive light from a light source, form a swath of illumination in a far field scene and to modulate phases of the light to sweep or steer the swath over the scene in two-dimensions (2D). An optical receiver in the scanner includes second phased-arrays to receive light from the far field scene and direct at least some of the light onto a detector. The second phased-arrays are configured to de-scan the received light by directing light reflected from the far field scene onto the detector while rejecting background light. In one embodiment the second phased-arrays direct light from a slice of the far field scene onto a 1D detector array.
