Abstract:
A device and method and system for utilizing confocal measurement and an optical arrangement to produce 3D color images. A color measurement optical path and a 3D measurement optical path may coincide at least at an object side of the device, and a minimal amount of light is extracted from a monitoring beam for color measurement without affecting 3D measurement.
