Abstract
Abstract A three-dimensional display apparatus is disclosed, having a fixed coded input source, a movable carriage carrying fiber optic elements with their input ends arranged adjacent the input source and their output ends arranged in a display face. In operation, the carriage is oscillated and a plurality of planes of an object are repeatedly displayed within a set volume by the input face, at a rate sufficient to prevent flicker.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
A three-dimensional display system, comprising a plurality of optical fibers each having a light receiving end and a light emitting end, means mounting said light emitting ends to form a display face on which an image is formed according to the illumination of said light receiving ends, and means mounting said light receiving ends in a fixed relationship to said display face and in a predetermined pattern in which each said end is positioned along a predetermined path that is independent of the means for moving said display face generally linearly in the direction of viewing through a volume at a sufficient rate to form a viewable three dimensional image from a succession of two dimensional images formed on said display face, means providing a coded representation of said succession of two dimensional images, means for effecting relative scanning movement between said light receiving ends and said coded representation means, and means for illuminating said light receiving ends at a succession of positions along said paths as said display face is moved through said volume in accordance with the coded representation of the two dimensional image corresponding to the position of the display face.
Claim 2
Dependent Claim
194 words
A three-dimensional display system, comprising a plurality of optical fibers each having a light receiving end and a light emitting end, means mounting said light emitting ends to form a display face on which an image is formed according to the illumination of said light receiving ends, and means mounting said light receiving ends in a fixed relationship to said display face and in a predetermined pattern in which each said end is positioned along a predetermined path that is independent of the means for moving said display face generally linearly in the direction of viewing through a volume at a sufficient rate to form a viewable three dimensional image from a succession of two dimensional images formed on said display face, means providing a coded representation of said succession of two dimensional images, means for effecting relative scanning movement between said light receiving ends and said coded representation means, and means for illuminating said light receiving ends at a succession of positions along said paths as said display face is moved through said volume in accordance with the coded representation of the two dimensional image corresponding to the position of the display face.
Claim 3
Dependent Claim
39 words
The display system of claim 1 wherein said means for illuminating said light receiving ends of said optical fibers comprises a source of light and a coded mask positioned between said source of light and said light receiving ends.
Claim 4
Dependent Claim
50 words
The display system of claim 1 wherein said pattern comprises a plurality of groups of fiber optics spaced apart in the direction of the scanning movement by at least the distance of said scanning movement to maintain the paths of one group independent of the paths of the other group.
Claim 5
Dependent Claim
22 words
The display system of claim 1 wherein said means providing a coded representation comprises an opaque sheet having coded light transmitting openings.
Claim 6
Dependent Claim
60 words
The display system of claim 4 wherein said openings are arranged in rows and columns in said sheet, each row corresponding to a two dimensional image plane, said Rows being arranged in the sequence in which said image planes are presented in said three dimensional image, the openings of each column corresponding to a particular point in said display face.
Claim 7
Dependent Claim
17 words
The display system of claim 5 wherein selected ones of said openings are elongated along said rows.
Claim 8
Dependent Claim
17 words
The display system of claim 5 wherein selected ones of said openings are elongated along said columns.
