Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 13:
14. A beam steering system, comprising:
a plurality of vertically stacked layers including a first layer configured to emit light at a first wavelength and a second layer disposed above the first layer and configured to emit light at a second wavelength different from the first wavelength; and
a control circuit coupled to the plurality of vertically stacked layers,
wherein each of the plurality of vertically stacked layers includes:
a light emission device including a plurality of light sources structured to generate a light beam and a light path selector coupled to the plurality of light sources and configured to provide a plurality of light paths to direct the light beam generated by the light source to a desired location;
an optical device located at a fixed position relative to the light emission device in optical paths of one or more optical beams from the light emission device, the optical device operable to collect received light; and
a plurality of light detectors arranged in rows and columns on the same focal plane as the plurality of light sources and spatially interleaved with the plurality of light sources, the plurality of light detectors configured to detect the received light, wherein transmission of the one or more optical beams by the plurality of light sources and reception of the received light by the plurality of light detectors occur simultaneously,
wherein the control circuit is coupled to the light emission device to select one or more of the plurality of light paths based on address information indicative of the location of incident light on the optical device,
wherein the one or more optical beams from the first and second layers are steered independently of or together with each other by the control circuit.
