Title:
LIDAR DEVICE COMPRISING LASER DETECTION ARRAY AND LASER OUTPUT ARRAY
Document Type and Number:
WIPO Patent Application WO/2024/096421
Kind Code:
A1
Abstract:
Disclosed is a method for a light detection and ranging (LiDAR) device to measure the distance from the LiDAR device to an object. Specifically, the method may include a LiDAR device: outputting a first laser beam through a vertical-cavity surface-emitting laser (VCSEL) in each of a plurality of scan cycles; identifying at least one time point at which at least one photon is detected through a single-photon avalanche diode (SPAD) optically corresponding to the VCSEL, in each of the plurality of scan cycles, in a time bin unit having a specific time interval; determining a histogram on the basis of the at least one time point; and measuring the distance between the object and the LiDAR device on the basis of at least a portion of the histogram.
