Claim 10:
11. A method of spatial profiling, the method including:
providing, by a light source, outgoing light having at least one time-varying attribute at a selected optical frequency channel of multiple selectable optical frequency channels;
spatially direct, by a beam director, the outgoing light into one of multiple directions into an environment having a spatial profile, the multiple directions corresponding to the multiple selectable optical frequency channels;
receiving, by a light receiver, at least part of the outgoing light reflected by the environment, the reflected light including a time delay relative to the outgoing light and a Doppler frequency shift relative to selected optical frequency channel of the outgoing light; and
determining, by a processing unit, for each one of the multiple selectable optical frequency channels, at least two characteristics associated with the reflected light, the at least two characteristics including (a) distance information based on the time delay and (b) velocity information based on the Doppler frequency shift, for estimation of the spatial profile of the environment associated with the corresponding multiple directions.
