Publication number: 20170045803Abstract: 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.Type: ApplicationFiled: August 11, 2015Publication date: February 16, 2017Inventor: Michael Braithwaite

Patent number: 8831416Abstract: A system and method for capturing an image for biometric identification. To obtain the image, a person stands or moves in a target zone. A flash element provides an incoherent flash of light through an aperture. The flash is filtered to produce filtered light. The filtered light has primary wavelengths no longer than that of blue light. The filtered light is not perceived well by the human eye due to its short duration, color and small point of origin. The intensity of the filtered light at the target area surpasses the intensity of all ambient light. In this manner, a person in the target area will always be properly illuminated, even if that person were backlit by full sunlight. An image of the person is taken with a camera. The image is analyzed to obtain any biometric patterns that can be used for identification.Type: GrantFiled: July 25, 2012Date of Patent: September 9, 2014Inventors: Michael Braithwaite, Andrew Philip Govan Date, Mohamed Nabil Moustafa, Jason Chaikin
