Abstract
Abstract Apparatus for producing a plurality of images of different colors from a polychromatic image comprising an image dissector which splits the image into separate beams, a dispersing prism dispersing the beams into beams of differing colors and a light guide designed to the dissector and prism to gather the beams of each individual color and combine same into a colored image at the output end of the light guide.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
133 words
Apparatus for the separation of a polychromatic image into a plurality of separate component images of different chromatic characteristics, comprising a fiber optic image splitter formed from a coherent bundle of light conductive fibers having an input end and an output end, and a dispersing arrangement for dispersing the polychromatic image into a plurality of beams of light of different chromatic characteristics and projecting such beams on to the input end of said bundle, the dispersing arrangement and the fibers being arranged such that beams of light of the same wavelength fall on to fibers which are grouped together at the output such that a component image of light of each wavelength is formed at the output end, and each component image is formed at its own individual region of the output end.
Claim 2
Dependent Claim
133 words
Apparatus for the separation of a polychromatic image into a plurality of separate component images of different chromatic characteristics, comprising a fiber optic image splitter formed from a coherent bundle of light conductive fibers having an input end and an output end, and a dispersing arrangement for dispersing the polychromatic image into a plurality of beams of light of different chromatic characteristics and projecting such beams on to the input end of said bundle, the dispersing arrangement and the fibers being arranged such that beams of light of the same wavelength fall on to fibers which are grouped together at the output such that a component image of light of each wavelength is formed at the output end, and each component image is formed at its own individual region of the output end.
Claim 3
Dependent Claim
59 words
Apparatus according to claim 1, wherein the input ends of the fibers are arranged in layers and the dispersing arrangement is such that the beams of light are lined extending transverse to the direction of dispersion so that lines of light of the same wavelength fall on the layers of fibers which are grouped together at the output end.
Claim 4
Dependent Claim
30 words
Apparatus according to claim 2, wherein the dispersion arrangement includes image dissection means for separating the polychromatic image into lines spaced in a direction transverse to the direction of dispersion.
Claim 5
Dependent Claim
19 words
Apparatus according to claim 3, wherein the image dissecting means comprises light conducting optical fibers are ranged in layers.
Claim 6
Dependent Claim
30 words
Apparatus according to claim 4, wherein the dispersion arrangement includes a prism for splitting the lines of light from the image dissecting means into lines of light of different wavelengths.
Claim 7
Dependent Claim
17 words
Apparatus according to claim 3, wherein there is wavelength multiplexing means provided with said image dissecting means.
Claim 8
Dependent Claim
38 words
Apparatus according to claim 1, wherein there is optical filter means adjacent each image region of the output end of optic image splitter, each filter means being for filtering light other than the light of the desired wavelength.
Claim 9
Dependent Claim
11 words
Apparatus according to claim 1, wherein the optical fibers are flexible.
Claim 10
Dependent Claim
17 words
Apparatus according to claim 1, wherein there is wavelength multiplexing means associated with said optical image splitter.
Claim 11
Dependent Claim
117 words
A television camera comprising a fiber optic image splitter formed from a coherent bundle of light conductive fibers having an input end and an output end, and a dispersing arrangement for dispersing a polychromatic image into a plurality of beams of light of different chromatic characteristics and projecting such beams on to the input end of said bundle, the dispersing arrangement and the fibers being arranged such that beams of light of the same wavelength fall on to fibers which are grouped together at the output such that a component image of light of each wavelength is formed at the output end, and each component image is formed at its own individual region of the output end.
Claim 12
