Abstract: A LIDAR system includes a laser source configured to generate laser light pulses, a first DMD, a second DMD and a two-dimensional (2D) sensor array. The first DMD is configured to receive the laser light pulses and diffractively steer the light pulses to sequentially illuminate different sub-regions within the extended region. The second DMD is configured to receive reflected light pulses from the different sub-regions in a sequential manner as each of the different sub-regions is illuminated by the light pulses. The 2D sensor array configured to receive reflected light pulses from the second DMD and form an image of the different sub-regions as the reflected light pulses from each of the different sub-regions is sequentially received from the second DMD.

Abstract: A system and method for real-time, simultaneous, and adaptive beam steering into multiple regions of interest replaces conventional raster scanning, where only regions of interest are scanned by a laser or other optical beam. CUDA-OpenGL interoperability with a computationally time-efficient computer-generated hologram (CGH) calculation algorithm enables such beam steering by employing a phase-spatial light modulator (SLM). The real-time CGH generation and display algorithm is incorporated into the beam steering system with variable power and scan resolution, which are adaptively controlled by camera-based object recognition.
