ABSTRACT:
A compact, two-dimensional full-frame document illumination and imaging device is formed by combining a short focal length imaging area array, such as a gradient index fiber lens area array, with a light source formed in the fiber interstitial areas of the array. The light source is addressed to provide a uniform illumination level at a document platen interface. The full document image is reflected back to the array and projected onto a photosensitive image plane.
