Classification: CPC G | IPC G

Claim 0:
1. A method, comprising:
transmitting, with a light source, a pulse group signal, wherein the pulse group signal comprises a plurality of pulses having a characteristic;
receiving a returned pulse group signal, wherein the returned pulse group signal corresponds to the transmitted pulse group signal scattered from a surface;
correlating the returned pulse group signal with the transmitted pulse group signal based on the characteristic;
determining a time difference between (1) a time associated with the transmitted pulse group signal and (2) a time associated with the returned pulse group signal;
calculating a distance from the light source to the surface based on the time difference; and
determining a reflectivity of the surface based on a correlation of the characteristic of the pulse group signal with the characteristic of the returned pulse group signal wherein the characteristic includes an amplitude of a correlation peak.
