    Patent number: 4613205
    Abstract: A method of fabricating an image fiber base material having a number of longitudinally drawn and aligned state optical fiber strands comprising the steps of assembling optical fiber strands of more than two different diameters. This eliminates the drawbacks of the conventional image fiber by arranging the cores at random and can reduce a moire produced when connecting to a TV camera, and does not produce dislocations or pinholes of core arrangement in the image fiber since a number of cores of the image fiber are arranged at random and are covered with an integrated cladding.
