Abstract: A system and method is provided for improving the visibility of hair on the skin surface, in a region that is bloodied or bruised, and potentially expanding the candidate pool of the hair grafts to be selected for harvesting. The system uses a light source comprising at least two emitters and the method comprises controlling the contrast between the image of the blood and the image of the skin surface. The method of the present invention may be implemented with various hair harvesting and transplantation systems, including manual, partially automated and fully automated systems.

Abstract: A flying spot system uses a laser beam scanned in X and Y directions to provide surface profile information. The beam is applied to a surface under test and the time interval between the beginning of the sweep and the appearance of the beam image through an aperture is determined. This time interval is indicative of the beam angle which, through optical triangulation, is used to determine the surface height. A scan-descan arrangement and a plate with a small aperture are used to isolate a light detector from background light.
