Abstract
Abstract A fiber optic faceplate for an electron tube in which an electron sensitive phosphor is provided on the inner surface of the faceplate and the light image from the phosphor is viewed or coupled through the fiber optic faceplate to an image intensifier. By providing an electrical conductive coating on the outer surface of the fiber optic faceplate, an improved fiber optic faceplate assembly is provided.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
An electron tube assembly comprising an evacuated envelope and having a fiber optic output window, said fiber optic output window having an electron responsive layer deposited on the inner surface of said fiber optic output window, a first terminal connected to said electron responsive layer, an outer electrically conductive layer provided on the outer surface of said fiber optic output window, a second terminal connected to said outer electrical conductive layer, said first terminal connected to said second terminal.
Claim 2
Dependent Claim
79 words
An electron tube assembly comprising an evacuated envelope and having a fiber optic output window, said fiber optic output window having an electron responsive layer deposited on the inner surface of said fiber optic output window, a first terminal connected to said electron responsive layer, an outer electrically conductive layer provided on the outer surface of said fiber optic output window, a second terminal connected to said outer electrical conductive layer, said first terminal connected to said second terminal.
Claim 3
Dependent Claim
41 words
The assembly in claim 1 in which said electron responsive layer is a layer of phosphor which emits light in response to electron bombardment and in which an inner electrically conductive coating is provided over the surface of the phosphor layer.
Claim 4
Dependent Claim
18 words
The device in claim 2 in which said first and second terminals are connected to the same potential.
Claim 5
Dependent Claim
22 words
The assembly in claim 2 in which said outer electrically conductive layer is transmissive to the light emitted by said phosphor layer.
Claim 6
Dependent Claim
152 words
An electronic imaging system comprising an image intensifier tube comprising a photocathode and an output phosphor, a first means for operating said output phosphor at a more positive potential than said photocathode, a fiber optic output window on said image intensifier, a camera tube having a fiber optic input window for viewing the output from said image intensifier, a fiber optic spacer member positioned between said output fiber optic window of said image intensifier and said fiber optic input window of said camera tube, said camera tube having a photocathode provided on the inner surface of said input fiber optic window, a second means for operating said photocathode of said camera tube at a negative potential with respect to said output phosphor on said image intensifier and an electrical conductive coating transmissive to the emission from said output phosphor positioned between said fiber optic output window and said fiber optic spacer member.
Claim 7
Dependent Claim
152 words
An electronic imaging system comprising an image intensifier tube comprising a photocathode and an output phosphor, a first means for operating said output phosphor at a more positive potential than said photocathode, a fiber optic output window on said image intensifier, a camera tube having a fiber optic input window for viewing the output from said image intensifier, a fiber optic spacer member positioned between said output fiber optic window of said image intensifier and said fiber optic input window of said camera tube, said camera tube having a photocathode provided on the inner surface of said input fiber optic window, a second means for operating said photocathode of said camera tube at a negative potential with respect to said output phosphor on said image intensifier and an electrical conductive coating transmissive to the emission from said output phosphor positioned between said fiber optic output window and said fiber optic spacer member.
Claim 8
Dependent Claim
