Abstract
An image fiber includes plural kinds of cores and a common cladding containing the cores, which are arrayed so that no similar cores are adjacent one another. A method of making the image fiber is that a plurality of optical fiber elements having cores of different diameters are arranged so that no similar cores are adjacent one another, and after being inserted in a jacket pipe, are heated at a high temperature to fuse the cladding portions of the optical fiber elements so that the whole is drawn down to a desired thickness.
