    摘要： Examples of a three-dimensional (3D) optical sensing system for a vehicle include a modular architecture. Light can be transmitted to an optical signal processing module, which can include a photonic integrated circuit (PIC) that can create one or more signals with tailored amplitude, phase, and spectral characteristics. The plurality of optical signals processed by the optical signal processing module can be sent to beam steering units distributed around the vehicle. The steering units can direct a plurality of optical beams towards targets. The return optical signal can be detected by a receiver PIC including an array of sensors and using a direct intensity detection technique or a coherent detection technique. The return optical signal can be converted into an electrical signal by the array of sensors, which can then be processed by the electronic signal processing unit, and information about the location and speed of the targets can be quantified.

    摘要： An integrated light detection and ranging (LiDAR) architecture can contain a focal plane transmitter array, and a focal plane coherent receiver for which the number of receiving elements is the same as the number of emitting elements. A microlens array may be used to achieve parity between the number of receiver and transmitter elements. The integrated LiDAR transmitter can contain an optical frequency chirp generator and a focal plane optical beam scanner with integrated driving electronics. The integrated LiDAR receiver architecture can be implemented with per-pixel coherent detection and amplification.

    摘要： Described are various configurations for transmitting and receiving optical light using a shared path ranging system. The shared path ranging system can include an optical router (e.g., an optical coupler) coupled to a grating to transmit light to a physical object and receive light reflected by the physical object. The shared path ranging system can include rows of routers and gratings in a two-dimensional configuration to transmit and receive light for ranging purposes.
