Abstract
A light detection and ranging (LiDAR) device may include: an optical phased array configured to modulate a phase of light incident on the optical phased array and emit the light; a first photodetector configured to detect, as a reference light, the light emitted from the optical phased array in a first direction toward the first photodetector, and generate a reference signal based on the reference light; a second photodetector configured to detect, as a target light including information about an object, the light emitted from the optical phased array in a second direction toward the object, and generate a target signal based on the target light; and a processor configured to determine a distance between the LiDAR device and the object based on a cross-correlation between the reference signal and the target signal.
