Claim 8:
9. The method of claim 1, wherein the transmitted pulse group signal is a first pulse group signal, the method further comprising:
transmitting a second pulse group signal, wherein the second pulse group signal comprises a second plurality of pulses having a second characteristic;
receiving a second returned pulse group signal, wherein the returned pulse group signal corresponds to the second pulse group signal scattered from a second surface;
correlating the second returned pulse group signal with the second pulse group signal based on the second characteristic;
determining a second time difference between (1) a time associated with the second pulse group signal and (2) a time associated with the second returned pulse group signal;
calculating a second distance from the light source to the second surface based on the second time difference; and
determining a reflectivity of the second surface based on a correlation of the second characteristic of the second pulse group signal with the characteristic of the second returned pulse group signal.
