LiDAR device and method of operating the same

A light detection and ranging (LiDAR) device comprising:

• a light transmitter comprising a plurality of light sources that comprises a first light source and a second light source, each of the plurality of light sources being configured to emit light toward an object;
• a light receiver comprising a plurality of light detection elements that comprises a first light detection element and a second light detection element, each of the plurality of light detection elements being configured to detect reflected light reflected from the object that is irradiated with the light emitted by the plurality of light sources;
• and
• a processor configured to obtain information on the object,
• wherein the first light detection element is configured to receive a first reflected light reflected from the object that is irradiated with a first light emitted by the first light source among the plurality of light sources, and to output first detection information corresponding to the first reflected light,
• wherein the second light detection element is configured to receive a second reflected light reflected from the object that is irradiated with a second light emitted by the second light source among the plurality of light sources, the second light source being different from the first light source,
• wherein the second light detection element outputs second detection information based on the second reflected light and a crosstalk generated,
• wherein the light receiver further comprises:
• a first detection signal converter configured to convert the first detection information output by the first light detection element into a first pulse signal;
• a second detection signal converter configured to convert the second detection information output by the second light detection element into a second pulse signal;
• and
• a crosstalk removing element configured to receive the first pulse signal and the second pulse signal, identify a crosstalk in the second pulse signal based on a determination that a pulse corresponding to at least one of a reception time point, a pulse width, and a pulse size, of a pulse included in the first pulse signal, is included in the second pulse signal, and remove the identified crosstalk from the second pulse signal, and
• wherein the processor is further configured to obtain the information on the object based on the second detection information, from which the crosstalk has been removed.
