Title:
APPARATUS FOR LIGHT DETECTION AND RANGING
Document Type and Number:
WIPO Patent Application WO/2023/206352
Kind Code:
A1
Abstract:
An apparatus (102) for light detection and ranging (LiDAR) includes a light detector with a pixel array (106) configured to detect photons from incident light. Further, the apparatus (102) includes a time-measuring circuit (108) that is disposed outside the pixel array (106). The time-measuring circuit (108) is configured to store a single timestamp value when any pixel in the pixel array (106) is hit by a photon at a given time. Further, the apparatus (102) includes a plurality of shift registers that are configured to store timestamp addressing data for each pixel that is hit by a photon and a processing unit (112) to co-relate the timestamp value with the timestamp addressing data for each pixel for distance measurement or object detection. Therefore, the apparatus (102) is beneficial to improve the reliability, resolution, and performance of the LiDAR systems with reduced power consumption.
