ABSTRACT:
A photo imaging system includes a two-dimensional lens array for forming an image of an object on a receptor element. The lens array includes a number of optical glass fibers which are mounted in rows between supporting plates so that each row is adjacent to a plate. This causes the optical fibers to be supported in a parallel manner to reduce distortion which is caused by unsupported bending or flexing of the fibers. Since the lens array and receptor element remain fixed relative to each other during image formation, formation of a complete image of the object is achieved by providing a lens array having a sufficient number of fiber rows.
