Image transmitter formed of a plurality of graded index fibers in bundled configuration
TLDR
In this paper, an optical device for transmitting an image wherein a number of optical fibers are disposed in such a manner that they are arranged neatly in the same relative position among them, at least, both ends thereof, each of said fibers having such a refractive index distribution as to substantially satisfy the equation n = N (1 - ar2) in a cross section triangle, where n is a center, r is a distance r from the center, and a is a positive constant, whereby light due to an object placed at one end of the optical fibers forms an image ofAbstract:

Method of manufacturing a transparent light conducting element of synthetic resin having refractive index gradient
Yasuji Ohtsuka,Motoaki Yoshida +1 more
TL;DR: In this article, a method of manufacturing a light conducting element of synthetic resin in which a continuous change takes place in refractive index from the surface of the element toward its interior, which comprises bringing a transparent solid article of a network polymer which is in the incompletely polymerized state and contains 2 to 80% of a solvent-soluble component, into contact at its surface with a monomer capable of forming a polymer having a different refractive indices from the network polymer thereby to cause the diffusion and migration of the monomer into the interior of the article through the contact surface,
