1. An optical method of determining the color and profile of a target surface comprising the steps of:
- (a) scanning the target surface with an incident beam of light containing a plurality of wavelengths including at least one well defined wavelength;
(b) splitting a return beam that has reflected from the target surface into a plurality of separate return beams including at least a first and second return beam;
(c) utilizing the first return beam that has reflected from the target surface for detecting the profile of the target surface;
(d) utilizing the second return beam to detect color information corresponding to the target surface;
(e) providing the second return beam to a means for detecting one or more of red, green, and blue spectral contents; and
(f) generating signals representative of the respectively colored spectral content of the second return beam from the target surface.

Abstract
An optical method and apparatus is provided for determining the color and profile of a target surface of an object. The target surface is scanned with an incident beam of light containing a plurality of wavelengths including at least one well defined wavelength. A return beam reflected from the target is split into at a first and second return beam. The first return beam is utilized for detecting the profile of the target surface; and, a plurality of detectors are provided that detect color information corresponding to the target surface from the second return beam.
