Abstract

The subject matter of this specification can be implemented in, among other things, systems and methods that enable lidar channel multiplexing using optical locking of separate lasers while simultaneously imparting different frequency offsets to beams output by different lasers. As a result, received beams reflected from various objects, which are present in an outside environment, can have Doppler-shifted frequencies that do not overlap, facilitating concurrent identification of distances to and velocities of multiple objects.
