Application of gradient-index fiber arrays to copying machines.
A gradient-index fiber array arranged in a plurality of rows, which forms an erect image with unit magnification, is employed as a novel optical system for use in a copying machine. In this paper, the optical characteristics of the fiber array are discussed. In particular, an equation indicating the quantity of light for slit-exposure scanning is introduced. The f/No. of the N-row array is defined in a form equivalent to the f/No. of a conventional lens.
