ABSTRACT:
An apparatus for illuminating and imaging a surface includes a two-dimensional array of LEDs for providing uniform illumination to the surface, the LEDs being mounted on a planar surface with a centrally defined aperture, and a CCD-based camera with appropriate lensing for obtaining an image of the illuminated surface and providing a signal representative of that obtained image to a processing unit, the CCD-based camera lensing being disposed through the centrally defined aperture in the planar surface of the LED array, and the LED array and CCD-camera lensing being disposed inside an opaque shroud.
