Abstract
Abstract An electro-optical imaging device has a target with an imagereceiving surface (e.g., electrons or photon sensitive) primarily designed to be disposed within an image which is substantially spatially fixed with respect to the surface and has a substantially time invariant outline.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
73 words
In an electro-optical image device having a target with an image-receiving surface, and an optical system for imaging onto said surface an image which has a substantially time invariant outline and is substantially spatially fixed with respect to said surface so that said outline will cover only a portion of said surface, the improvement characterized in that substantially only the portion of said surface which receives said image is provided with image-translating material.
Claim 2
Dependent Claim
73 words
In an electro-optical image device having a target with an image-receiving surface, and an optical system for imaging onto said surface an image which has a substantially time invariant outline and is substantially spatially fixed with respect to said surface so that said outline will cover only a portion of said surface, the improvement characterized in that substantially only the portion of said surface which receives said image is provided with image-translating material.
Claim 3
Dependent Claim
19 words
An electro-optical imaging device as defined by claim 1 wherein said each such image translating material is electron sensitive.
