Abstract: A hand-held vision sensor apparatus comprises a plurality of light sources, control activation elements and an image sensing array, encased within a housing such that the control activation elements are disposed at a user-accessible location on the housing. The housing further includes a pair of exit apertures for emitting illumination directed toward a medical specimen and an entrance aperture for capturing reflected light from the medical specimen. The light sources are disposed in alignment with the pair of exit apertures, and the image sensing array is aligned with the entrance aperture. The control activation elements are utilized to energize the light sources and control the functioning of the image sensing array. A computer port may be included and used to communicate command controls to the light sources, image sensing array and control activation elements in a manner that allows for a remotely-located technician to communicate with the hand-held vision sensor.
