    摘要: 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.

    摘要: An optical scanner includes at least one light source configured to emit light, a steering unit configured to perform scanning in a first direction based on the light emitted from the at least one light source, and a polygon mirror configured to perform, by using the light output from the steering unit, scanning in a second direction different than the first direction based on a rotation of the polygon mirror. The steering unit includes a plurality of first prisms, and each of the plurality of first prisms includes an incident facet configured to pass the light emitted from the at least one light source, and an output facet configured to refract and output the light. The polygon mirror includes a plurality of reflective facets, and each of the plurality of reflective facets is configured to that reflect the light output from the steering unit.
