FMCW automotive lidar
Described by its proponents as a superior form of sensor for automotive applications, FMCW lidar uses a continuous-wave laser source to scan the surroundings of a vehicle, rather than a pulsed source to generate a point cloud. Although more technologically complex than time-of-flight sensors, this approach yields instant data on the range, velocity, and direction of other objects on the road. Aeva, one of a few companies working on FMCW hardware (two of its sensors can be seen on the roof of the car in the image), has struck a deal with German parts giant ZF that aims to bring the technology to mass production.
