  • MULTI-CHANNEL LIDAR OPTICAL SUB-ASSEMBLY WITH SHARED OPTICS
    Publication number: 20210063541
    Abstract: An optical device may include a laser component to emit a source beam and an optical component to split the source beam to generate a first beam and a second beam. The optical device may include a multiplexing component to multiplex the first beam and the second beam to form a first multiplexed beam, an optical system to receive the first multiplexed beam and demultiplex the first beam and the second beam, and a scanning component to scan a field of view with the first beam and the second beam and receive the first beam and the second beam reflected from the field of view. The optical system may multiplex the first beam and the second beam reflected from the field of view to form a second multiplexed beam, and a demultiplexing component may demultiplex the first beam and the second beam reflected from the field of view.

  • Method and controller for operating a variable optical retarder and an array
    Patent number: 10031397
    Abstract: A method and a controller for operating an array of variable optical retarders are disclosed. Neighboring pixels of the array of variable optical retarders are driven with disordered temporal bit sequences. An optical beam illuminating the pixels tends to integrate time-domain modulation caused by individual pixels driven in a non-coordinated or disordered fashion, which reduces the overall time-domain modulation amplitude of the optical beam.
