Abstract

See full text

A lidar device includes a light source configured to emit a laser pulse to an object, a light receiver configured to receive the laser pulse reflected by the object, a first periodic wave generator configured to generate a first periodic wave when the light source emits the laser pulse and generate a second periodic wave when the light source receives the laser pulse, and a first comparator configured to compare a phase of the first periodic wave and a phase of the second periodic wave to each other. The lidar device calculates a distance between the lidar device and the object based on a phase difference determined by the first comparator.
