Abstract
An illumination and imaging system that is used to obtain enhanced detailed images of objects. The system utilizes a flash element that produces a flash of polychromatic light. A plurality of fiber optic elements are provided that terminate with output ends. At least some of the fiber optic elements are doped to be different colors. Consequently, when each fiber optic element receives the flash of polychromatic light from the flash element, that fiber optic element propagates and filters the polychromatic light to produce colored filtered light. The colored filtered light is directed toward the object being imaged by the camera. The illumination has small points of origin, different color characteristics and simultaneous short flash duration. The combination of colored, directional light sources enables the camera to image very fine details by enhancing surface texture and embedding the image with the color photometric stereo information.
