Abstract
A machine includes an enclosure having a double layer wall including an outer wall that provides mechanical protection and protection from dust, fluids and environmental factors and an inner wall having a gradient change in reflectance with height within the enclosure; a lens coupled to the enclosure, the lens defining an optic axis-within the enclosure parallel to the gradient change in reflectance with height; a camera coupled to the lens; an image processing circuit coupled to the camera; and a plurality of light sources coupled to the enclosure, the plurality of light sources defining a plurality of illuminant axes located substantially symmetrically around and parallel to the optic-axis. Each of the plurality of light sources includes a plurality of independently controllable segments located along the illuminant axes so an angle of illumination from the plurality of light sources to the optic axis can be controlled.
