Embodiment Construction

[0045] Reference will now be made in detail to example embodiments illustrated in the drawings, wherein like reference numerals refer to like elements throughout, and the dimensions of elements may be exaggerated for clarity. In this regard, example embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the example embodiments are merely described below, by referring to the figures, to explain various aspects. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Expressions such as "at least one of," when preceding a list of elements modify the entire list of elements and do not modify the individual elements of the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, Or include all of a, b, and c.

Abstract

Provided in a light detection and ranging (LiDAR) device including a scanning optical system including a plurality of light sources and a beam steering device, the scanning optical system being configured to scan an object with a plurality of irradiation beams projected from the plurality of light sources toward the object at a plurality of irradiation angles, respectively, a light detector including a plurality of pixel regions that are configured to separately detect the plurality of irradiation beams projected toward the object at the plurality of irradiation angles and reflected from the object, and a processor configured to control the scanning optical system and the light detector, and obtain information about the object based on the plurality of irradiation beams detected by the light detector.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0153716 filed with the Korean Intellectual Property Office on December 3, 2018, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] Example embodiments of the present disclosure relate to a Light Detection and Ranging (LiDAR) device and a method of driving the LiDAR device. Background technique [0004] Light detection and ranging (LiDAR) systems are used in various fields such as aerospace, geology, 3D mapping, automotive, robotics and drones. [0005] The LiDAR system uses a method of measuring the time required for light to travel back and forth (hereinafter referred to as a time-of-flight (TOF) method) as a basic operating principle. That is, after emitting light toward an object, the sensor receives the light reflected from the object, and measures the TOF of the light using a high-speed c...
