Abstract
A LIDAR system that generates an outgoing LIDAR signal and multiple composite light signals that each carries a different channel and that each includes a contribution from a reference signal and a contribution from a comparative signal. The comparative signals each include light from the outgoing LIDAR signal that has been reflected by one or more objects located outside of the LIDAR system. The reference signals each include light from the outgoing LIDAR signal but exclude light that has been reflected by any object located outside of the LIDAR system. Electronics induce a frequency offset in the reference signals between a LIDAR data period and a channel period. The electronics use the composite signals generated during the LIDAR data period to generate LIDAR data and the composite signals generated during the channel period to associate the composite signals with the channel carried by the composite signal.
