Abstract: The present disclosure relates to systems and methods that provide both an image of a scene and depth information for the scene. An example system includes at least one time-of-flight (ToF) sensor and an imaging sensor. The ToF sensor and the imaging sensor are configured to receive light from a scene. The system also includes at least one light source and a controller that carries out operations. The operations include causing the at least one light source to illuminate at least a portion of the scene with illumination light according to an illumination schedule. The operations also include causing the at least one ToF sensor to provide information indicative of a depth map of the scene based on the illumination light. The operations additionally include causing the imaging sensor to provide information indicative of an image of the scene based on the illumination light.

Abstract: The present disclosure relates to optical receiver systems. An example optical receiver system includes a first substrate with a plurality of photodetectors and a bias circuit. The bias circuit is electrically coupled to each photodetector of the plurality of photodetectors. The bias circuit is configured to provide a bias voltage to each photodetector. The optical receiver system also includes a plurality of capacitors. Each capacitor of the plurality of capacitors is electrically-coupled to a respective photodetector of the plurality of photodetectors. The optical receiver system also includes a second substrate with a read-out circuit having a plurality of channels. Each channel of the plurality of channels is capacitively-coupled to a respective photodetector via the respective capacitor.
