Spatial light modulator retroreflector mitigation

A sensor system, comprising:

• an optical transmitter module, comprising:
• at least one light-emitter device, wherein the at least one light-emitter device comprises light-emitter devices arranged in a 1-dimensional array, and wherein the light-emitter devices are disposed along a shared light-emitter axis;
• and
• a plurality of micromirror devices optically-coupled to the light-emitter device, wherein the micromirror devices are arranged in a 1-dimensional array, wherein the micromirror devices are disposed along a shared micromirror axis, wherein the shared light-emitter axis and the shared micromirror axis are parallel, and wherein the light-emitter device is configured to emit respective light beams toward an environment via the micromirror devices, wherein the micromirror devices are configured to deflect the light beams;
• an optical receiver module, comprising:
• at least one detector device;
• and
• a controller having at least one processor and a memory, wherein the controller executes program instructions stored in the memory so as to carry out operations, wherein the operations comprise:
• causing at least one micromirror device of the plurality of micromirror devices to deflect at least a portion of at least one light beam.

A method comprising:

• causing a light-emitter device to emit a light beam toward an environment along a transmit axis via a micromirror device, wherein the light-emitter device comprises light-emitter devices arranged in a 1-dimensional array, wherein the light-emitter devices are disposed along a shared light-emitter axis, and wherein the micromirror device comprises a plurality of micromirror devices arranged in a 1-dimensional array, wherein the micromirror devices are disposed along a shared micromirror axis, wherein the shared light-emitter axis and the shared micromirror axis are parallel, and wherein the micromirror device is configured to deflect the light beam;
• receiving information indicative of a retroreflector object in the environment;
• and
• based on the received information, causing at least one micromirror device of the plurality of micromirror devices to deflect the light beam so that the light beam does not interact with the retroreflector object.
