Patent ID: 11971589
Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 7:
8. 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 light source array and a light source selector coupled to the light source array, the light source array including a plurality of light sources arranged in rows and columns, the light source selector being structured to select one or more light sources from the light source array to produce one or more optical beam;
an optical device located at a fixed position relative to the light emission device in optical paths of the 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 source selector of the light emission device to select the one or more light sources from the light source array based on address information indicative of the location of the light source associated with 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.
