US Patent 10557923 Real-time processing and adaptable illumination lidar camera using a spatial light modulator

An apparatus for illuminating or masking an object and a method of using same. The apparatus includes a spatial light modulator transmitting, a structured pulsed laser beam from a pupil plane to at least one image plane in a field of view. The apparatus further includes a lidar detector receiving reflected laser beam reflected from the at least one image plane. For example, the lidar detector detects range, position, and/or time data for at least one object of interest or at least one object of disinterest. Using the detected data, the spatial light modulator illuminates object of interest or masks an object of disinterest, depending on a user's application.
