Abstract
Abstract This invention relates to novel composite photoelectric screens characterized by the construction in which the supporting member for the photoelectric means is radiation transparent and is made of an array of said radiation-conducting fibers. The lightconducting fibers operate by the internal reflection and are arranged spatially in such a manner that they can transfer the radiation image across said support without any appreciable loss of resolution, contrast and brightness.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
174 words
A composite photoelectric screen comprising in combination photoelectric means and rigid supporting means, said supporting means transferring an image of electromagnetic radiation across their thickness and having a two-dimensional cross section and a two-dimensional end face, said supporting means comprising a plurality of fibers conducting said radiation by internal reflection, the ends of said fibers forming an end face of said supporting means, said ends being united together at said end face, said fibers constituted of a member of material transparent to at least a part of said conducted radiation and of a high index of refraction, said members having a smooth external surface reducing the escape of said radiation from said members, said members having coating means separating said members from each other, said coating means of material of a lower index of refraction than said members reducing further the escape of said radiation from said members, said coating means furthermore having the thickness not exceeding a few microns, said photoelectric means mounted on said end face and receiving said conducted image radiation.
Claim 2
Dependent Claim
174 words
A composite photoelectric screen comprising in combination photoelectric means and rigid supporting means, said supporting means transferring an image of electromagnetic radiation across their thickness and having a two-dimensional cross section and a two-dimensional end face, said supporting means comprising a plurality of fibers conducting said radiation by internal reflection, the ends of said fibers forming an end face of said supporting means, said ends being united together at said end face, said fibers constituted of a member of material transparent to at least a part of said conducted radiation and of a high index of refraction, said members having a smooth external surface reducing the escape of said radiation from said members, said members having coating means separating said members from each other, said coating means of material of a lower index of refraction than said members reducing further the escape of said radiation from said members, said coating means furthermore having the thickness not exceeding a few microns, said photoelectric means mounted on said end face and receiving said conducted image radiation.
