  • Method and apparatus for dynamic reconfiguration of region of interest in integrated FMCW LIDAR
    Patent number: 11879979
    Abstract: A dynamically reconfigurable Light Detection and Ranging (LiDAR) system can generate improved ranging data one or more regions of three-dimensional (3D) images generated by the system. The images can be segmented, and global or local optical characteristics (e.g., power, illumination duration, bandwidth, framerate frequency) of the light can be modified to increase the 3D image quality for the segments of the image.

  • BACKSIDE ILLUMINATION ARCHITECTURES FOR INTEGRATED PHOTONIC LIDAR
    Publication number: 20210257396
    Abstract: A single and dual path light detection and ranging (LiDAR) system can transmit and receive light through a silicon substrate backside of a photonic integrated circuit (PIC). The PIC can be interface with an electrical integrated circuit (EIC) using a front side that connects to the EIC using electrical contacts and a backside that faces away from the EIC. High density coupler elements (e.g., pixels, gratings) can emit and receive infrared light that propagates through the PIC layers and the backside towards objects to detection.

  • DUAL PATH LIGHT DETECTION AND RANGING SYSTEM
    Publication number: 20210141058
    Abstract: A dual path configuration Integrated LiDAR architecture can contain a focal plane transmitter and a focal plane coherent receiver. 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.
