  • Image reversing array utilizing gradient refractive index elements
    Patent number: 4258978
    Abstract: An array of optical elements having imaging properties in one meridian and light-containment properties in another meridian for imaging a slit aperture in such a way that inversion of the image occurs across the width of the slit but not along the length of the slit. This one-way image reversal may be used to improve efficiency in photocopying.
    Type: Grant
    Filed: December 5, 1978
    Date of Patent: March 31, 1981
    Assignee: American Optical Corporation
    Inventor: Henry B. Cole
  • Tapered fiber optic array
    Patent number: 4076378
    Abstract: A tapered fiber optic array for conveying light from one station to another with differently sized light reception and emission areas and precontrolled values of light receiving and emitting numerical aperture. The array comprises a unit of juxtapositioned multiple core, individually clad and tapered optical fibers. The taper ratio determines its light reception and emission area sizes while the refractive index values of individual fiber cores and cladding establish, in conjunction with the taper ratio, the numerical aperture characteristics.

  • Apparatus for making fiber optic devices
    Patent number: 4011069
    Abstract: Apparatus having a headstock and tailstock between which a shortened fiber optic image-inverter is formed by twisting and axially compressing a heated bundle of light-conducting fibers held by endpieces respectively supported in said headstock and tailstock; said endpieces being axially rotatable, one relative to the other, for twisting said bundle and moveable, one axially toward the other, for compression of said bundle.

  • Method of making microchannel plates
    Patent number: 4010019
    Abstract: Making glass microchannel plates by drawing bundles of large numbers of glass tubes sufficiently to reduce the cross-sectional sizes of openings through the tubes to desired microchannel size with minimal distortion of original tube shape and wall thickness in resulting assemblies. Drawing is accomplished with no less than two separate steps; a first step being effected with large pulling force and minimal heating and a second step effected with relatively small pulling force, heating to relatively high viscosity and rapid drawing for short exposure to heat.

  • Method of making fiber optic device
    Patent number: 3977855
    Abstract: A shortened image inverter formed of a plurality of light-conducting fibers arranged in side-by-side relationship with each other as a bundle having opposite image-receiving and image-emitting faces; the bundle being twisted intermediately of its opposite end faces by the amount of 180.degree. and compressed axially for shortening.
