Abstract: Provided are a LiDAR device and a method of operating the LiDAR device. The LiDAR device includes a light-emitting unit configured to emit modulated light onto an object, a light-receiving unit configured to receive the modulated light reflected by the object, a computation unit configured to calculate a distance to the object based on a reception signal of the modulated light provided by the light-receiving unit, a modulation unit configured to provide a modulation signal to the light-emitting unit to generate the modulated light, and a controller configured to control operations of at least one of the light-emitting unit, the light-receiving unit, the computation unit, and the modulation unit.

Abstract: Light detection and ranging (LiDAR) systems and methods of operating the LiDAR systems are provided. The LiDAR system includes a light emitter configured to emit first lights of different wavelengths in a vertical direction and at different scanning angles with respect to a horizontal axis, a lens configured to converge second lights that are reflected from objects on which the first lights are emitted, and a light filter comprising an active-type device configured to adjust a transmission central wavelength of the active-type device to the different wavelengths of the first lights that are emitted from the light emitter. The LiDAR system further includes a controller configured to control an operation of the light emitter and the light filter, and a detector configured to detect light from the light emitter, and obtain information about the objects.
