Abstract
A LIDAR includes multiple light sources and a Liquid Crystal on Silicon (LCOS) device for controllably redirecting beams from each of the multiple light sources. The same or a different LCOS device can be used to controllably redirect reflected light to each of several corresponding light detectors. The LCOS device can be adjusted on a slower time scale while the light sources can be sequentially activated on a faster time scale. The LCOS device provides for fine steering control of LIDAR beams. The use of multiple light sources and detectors allows for a higher LIDAR scan rate.
