Abstract
Abstract A method of hot rolling or extrusion of a textured-surface sheet can be used to produce a large one dimensional array of fibers; these arrays can be stacked to form the two dimensional matrix required for image transfer. Alternatively, a flat ribbon can be rolled or extruded and the fiber array formed from it by altering the refractive index of alternate strips using diffusion ion exchange or implantation methods.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
93 words
A method for producing a unitary ribbon like sheet of optic fiber which is effectively optically separated into a plurality of parallel optical paths, the method including the steps of: providing a source of optically transparent material heated to a plastic consistency; forming the optically transparent material into a ribbon like sheet; and, causing a reducing of the index of refraction along parallel narrow strips of the ribbon like sheet to thereby effectively divide the sheet into a plurality of optical fiber paths wherein said index is reduced by the strain induced effect.
Claim 2
Independent Claim
93 words

Claim 3
Dependent Claim
16 words
The method according to claim 1 in which the optically transparent material is a halide material.
Claim 4
Dependent Claim
24 words
The method according to claim 1 in which the optically transparent material is selected from a group consisting of silver halide and thallium halide.
Claim 5
Dependent Claim
17 words
The method according to claim 1 in which the optically transparent material is transparent at infrared wavelengths.
Claim 6
Dependent Claim
19 words
The method according to claim 1 in which the step of forming is by extruding the ribbon like sheet.
Claim 7
Dependent Claim
20 words
The method according to claim 1 in which the step of forming is by hot rolling the ribbon like sheet.
