16. A system, comprising:
a first LiDAR system configured to illuminate a field of view (FOV) with pulses of transmitted light having different wavelengths at different regions in the FOV;
a lens to focus incoming light into the first LiDAR system;
a diffraction optical element to diffract the focused light from the lens to generate signals having the different wavelengths to respective regions of a detector array, wherein each pixel position in the array corresponds to one of the different wavelengths and to a spatial location in the FOV; and
a processor to process data from the pixel array to discriminate any of the incoming light coming from systems other than the first LiDAR system.
