ABSTRACT:
A two-dimensional full frame illumination and imaging assembly is formed, in a preferred embodiment, by joining, in combination, a platen, platen housing extension and full frame lens array. The combined assembly is converted into a higly efficient, light directing cavity by making the sides of the platen and platen housing diffusely reflective. The top surface of the lens array, excluding the lenslet entrance aperture, is also made reflective. Light is then coupled into the housing through an aperture formed in at least one of the sides. The light undergoes multiple reflections from all sides of the assembly, providing illumination of the document whose relfection is transmitted by the lens array onto a photosensitive image plane.
