  • Publication number: 20230243940
    Abstract: Described herein is a time-of-flight ranging system and methods for its operation. The system includes an array of single photon avalanche diode (SPAD) pixels and control circuitry. The control circuitry simultaneously accumulates integrated SPAD event data from one cluster of SPAD pixels while integrating SPAD event data from another cluster during different target illuminations. The system also includes first and second VCSEL clusters, each responsible for a different target illumination. By processing and managing the data in this manner, the system can effectively reduce the time used to gather and analyze the event data, leading to faster and more accurate distance measurements.
