Full-frame short focal lenght imaging system.

摘要

A compact, two-dimensional full-frame document illumi- nation and imaging device is formed by combining a short focal length imaging area array (14), such as an array of gradient index fiber lenses (20), with a light source (24) formed in the fiber interstitial areas of the array. The light source is addressed to provide a uniform illumination level at the interface between a document (10) and a platen (12). The full document image is reflected back to the array and projected onto a photosensitive image plane (16).
