| Proponents of FMCW lidar say that the approach is able to deliver a superior combination of positional and velocity information about objects on the road, and enables systems that can be shrunk to the size of a chip. Shown here is a lidar chip produced by the venture-backed FMCW firm Aeva. However, the approach demands a narrow-linewidth laser source and coherent detection. Photo: Aeva. |
