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: One example system includes a light source that emits light. The system also includes a waveguide that guides the emitted light from a first side of the waveguide toward a second side of the waveguide opposite 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. 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: One example method involves obtaining a plurality of images using a camera located at a given position relative to a light detection and ranging (LIDAR) device. A first image of the plurality may be obtained while a first aperture is interposed between the camera and the LIDAR device. A second image of the plurality may be obtained while a second aperture is interposed between the camera and the LIDAR device. The method also involves determining one or more alignment offsets between a transmitter of the LIDAR device and a receiver of the LIDAR device based on the plurality of images.
