Abstract
A light detection and ranging system modulates laser light pulses with a channel signature to encode transmitted pulses with channel information. The modulated laser light pulses may be scanned into a field of view. Received reflections not modulated with the same channel signature are rejected. Multiple light pulses of different wavelengths may be similarly or differently modulated.
