Abstract: The present disclosure relates to limitation of noise on light detectors using an aperture. One example implementation includes a system. The system includes a lens disposed relative to a scene. The lens focuses light from the scene. The system also includes an opaque material that defines an aperture. The system also includes a waveguide having a first side that receives light focused by the lens and transmitted through the aperture. The waveguide guides the received light toward a second side of the waveguide opposite to the first side. The waveguide has a third side extending between the first side and the second side. The system also includes a mirror that reflects the guided light toward the third side of the waveguide. The system also includes an array of light detectors that detects the reflected light propagating out of the third side.

Abstract: One example system comprises a light source configured to emit light. The system also comprises a waveguide configured to guide the emitted light from a first end of the waveguide toward a second end of the waveguide. The waveguide has an output surface between the first end and the second end. The system also comprises a plurality of mirrors including a first mirror and a second mirror. The first mirror reflects a first portion of the light toward the output surface. The second mirror reflects a second portion of the light toward the output surface. The first portion propagates out of the output surface toward a scene as a first transmitted light beam. The second portion propagates out of the output surface toward the scene as a second transmitted light beam.

Abstract: The subject matter of this specification can be implemented in, among other things, systems and methods of optical sensing for pixel multiplexing and polarized beam steering. Described, among other things, is a system that includes a light source configured to generate a light and one or more optical devices, integrated on a photonic integrated circuit, configured to impart modulation to the generated light and deliver the modulated light to an interface coupling device. The interface coupling device can include a plurality of interface couplers (ICs), each IC configured to scatter the modulated light in a direction that makes at least 5 degrees with an optical axis of lens configured to transmit the light scattered by each IC along a respective direction of a plurality of directions.

The waveguide has a third side extending between the first side and the second side. The system also includes a mirror that reflects the guided light toward the third side of the waveguide. At least a portion of the reflected light propagates out of the waveguide toward a scene. The system also includes a light detector, and a lens that focuses light from the scene toward the waveguide and the light detector.

Abstract: Example embodiments relate to spinning lidars utilizing one or more secondary mirrors. An example embodiment includes a lidar system that includes a rotatable portion. The rotatable portion includes one or more light sources and one or more one or more detectors. The rotatable portion is configured to rotate about a rotational axis such that the one or more light sources are operable to emit light within an azimuthal 360 degree field of view. The 360 degree field of view comprises a primary field of view that is less than 360 degrees. The lidar system also includes at least one secondary mirror configured to reflect light initially emitted by the one or more light sources in a direction away from the primary field of view so as to redirect the light into a secondary field of view.
