Abstract

Abstract The invention includes an image converter or image intensifier for night reconnaissance in military applications or the like. It is a feature of the invention that a multicolored picture is produced. In one embodiment identical multicolored photographic film positives are pasted onto the front and back of a conventional black and white direct view electron tube. The films may be color transparencies. With special color patterns, it is possible to obtain a bright colored picture of a scene illuminated at very low light levels, e.g., at night. It is also a feature of the invention that special films are used with apparatus to vibrate the tube to produce a colored picture of improved resolution.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 252 words
A multicolor, low light, direct view device comprising: an evacuated envelope having a light transparent input fiber optics window and a parallel light transparent output window; a channeltype electron multiplier fixed in said envelope between and parallel to said windows; a photocathode fixed in said envelope in a plane parallel to said input window and said multiplier; a luminescent screen fixed in said envelope in a plane parallel to said output window between said multiplier and said output window; said input window including a first transparent layer having a plurality of small areas of at least two first colors, said first colors beiong different from each other and being located contiguous to each other over the total area of said first layer, said first colors being uniformly distributed over the total area of said layer; said output window including a second transparent layer having a plurality of small areas of second colors, said second colors being different from each other and being located contiguous to each other over the total area of said second layer, each small area in said first layer having a corresponding small area in said second layer of the same size and location, all of the small areas of said first layer having one color only also having corresponding small areas in said second layer of one color only, said layers being fixed relative to said envelope, all the small areas of said layers being in axial alignment with each other; and carrier means to support said envelope.
Claim 2
Dependent Claim 252 words
A multicolor, low light, direct view device comprising: an evacuated envelope having a light transparent input fiber optics window and a parallel light transparent output window; a channeltype electron multiplier fixed in said envelope between and parallel to said windows; a photocathode fixed in said envelope in a plane parallel to said input window and said multiplier; a luminescent screen fixed in said envelope in a plane parallel to said output window between said multiplier and said output window; said input window including a first transparent layer having a plurality of small areas of at least two first colors, said first colors beiong different from each other and being located contiguous to each other over the total area of said first layer, said first colors being uniformly distributed over the total area of said layer; said output window including a second transparent layer having a plurality of small areas of second colors, said second colors being different from each other and being located contiguous to each other over the total area of said second layer, each small area in said first layer having a corresponding small area in said second layer of the same size and location, all of the small areas of said first layer having one color only also having corresponding small areas in said second layer of one color only, said layers being fixed relative to said envelope, all the small areas of said layers being in axial alignment with each other; and carrier means to support said envelope.
Claim 3
Dependent Claim 16 words
The invention as defined in claim 1, wherein said layers are color transparencies of photographic film.
Claim 4
Dependent Claim 33 words
The invention as defined in claim 2, wherein said small areas are colored red, green and blue, said red, green and blue areas being uniformly distributed over the total areas of said layers.
Claim 5
Dependent Claim 43 words
The invention as defined in claim 3, wherein said small areas are rows of equilateral hexagons every third one of which is the same color, the same color in one row being located midway between the same colors in the next adjacent row.
Claim 6
Dependent Claim 25 words
The invention as defined in claim 1, wherein said carrier means includes means to move said envelope in a direction perpendicular to its viewing axis.
Claim 7
Dependent Claim 25 words
The invention as defined in claim 5, wherein said carrier means includes means to reciprocate said envelope in a direction perpendicular to its viewing axis.
Claim 8
Dependent Claim 25 words
The invention as defined in claim 6 wherein said carrier means includes a base, and spring means to hold said envelope away from said base.
Claim 9
Dependent Claim 62 words
The invention as defined in claim 7 wherein said small areas of both of said layers are contiguous strips of uniform width running perpendicular to the direction of reciprocation of said envelope, said strips being red, green and blue, every third strip being red and having a blue strip on one side thereof and a green strip on the other side thereof.
Claim 10
Dependent Claim 64 words
The invention as defined in claim 1, wherein said carrier means includes means to reciprocate said envelope in a direction perpendicular to its viewing axis, said small areas of both of said layers being contiguous strips running perpendicular to the direction of reciprocation, each strip having a uniform width throughout its entire length, all the strips of the same color having the same width.
Claim 11
Dependent Claim 38 words
The invention as defined in claim 9 wherein said strips are red, green and blue, every third strip being red and having a blue strip on one side thereof and a green strip on the other side thereof.
Claim 12
Dependent Claim 32 words
The invention as defined in claim 1, wherein said carrier means includes means to move said envelope in a direction perpendicular to its viewing axis at substantially constant velocities in both directions.
Claim 13
Dependent Claim 62 words
ThE invention as defined in claim 11, wherein said small areas of both of said layers are contiguous strips of uniform width running perpendicular to the direction of reciprocation of said envelope, said strips being red, green and blue, every third strip being red and having a blue strip on one side thereof and a green strip on the other side thereof.
Claim 14
Dependent Claim 98 words
The invention as defined in claim 1, wherein said carrier means includes means to reciprocate said envelope in a direction perpendicular to its viewing axis, said small areas of both of said layers being contiguous strips of uniform width running perpendicular to the direction of reciprocation, said strips being arranged in identical groups of three different colors, each color having the same strip width, said reciprocation means being adapted to reciprocate said envelope a maximum distance in one direction equal to 3nW, where n is any positive integer and W is the width of one of said strips.
