Abstract
A device for scanning frequency-modulated continuous wave (FMCW) LiDAR range measurement has a light source producing light having a varying frequency, a splitter splitting the light into reference light and output light, and an optical system having an optical axis. A plurality of free space couplers are arranged along a line such that the distance between adjacent free space couplers increases with increasing distance from the optical axis. Each free space coupler outcouples the output light into the free space and receives input light that was reflected at an object. A detector detects a superposition of the input light with the reference light, and a calculation unit determines the range to the object from the superposition detected by the detector.
