Abstract
Abstract A system for displaying three dimensional images in conventional standard stereo pairs in which the displayed image may be conventionally viewed as a three dimensional object by appropriately channelling the individual ones of the stereo pairs each to a different eye of the viewer. The stereo pairs are generated without the use of two cameras, but rather with use of an energy detector such as a single photomultiplier tube or other photosensor devices and with a pair of spaced energy sources such as light beams that scan the object. Thin beams of light such as laser beams may be used as energy sources.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A three dimensional display system comprising a pair of spaced means for independent raster scanning of an object with a beam of energy, detector means for independently receiving reflected signals from each of said spaced scanning means, means for synchronizing the movement of beams of energy from said independent raster scanning means, means for generating output images from said receiving means in which said output images are generated from said independent signals and form a pair of stereopically related images.
Claim 2
Dependent Claim
80 words
A three dimensional display system comprising a pair of spaced means for independent raster scanning of an object with a beam of energy, detector means for independently receiving reflected signals from each of said spaced scanning means, means for synchronizing the movement of beams of energy from said independent raster scanning means, means for generating output images from said receiving means in which said output images are generated from said independent signals and form a pair of stereopically related images.
Claim 3
Dependent Claim
46 words
A three dimensional display system as set forth in claim 1, wherein means are provided to generate said pair of stereoscopically related images on a cathode ray tube whose electron beam raster is synchronized with said raster scanning of the object with independent beams of energy.
Claim 4
Dependent Claim
32 words
A three dimensional display system as set forth in claim 2, wherein means are provided for visually segregating for separate viewing, one by each eye, of said pair of steropically related images.
Claim 5
Dependent Claim
37 words
A three dimensional display as set forth in claim 2 wherein said spaced means include means for generating a beam in the visible light frequency of the energy spectrum and said detector means comprises a photomultiplier tube.
Claim 6
Dependent Claim
83 words
A three-dimensional display system comprising a pair of means for generating beams of energy, means for raster scanning of an object with each of said beams, means for detecting said beams of energy reflected from said object with the reflected beam from one generating means segregated from the reflected beam from the other generating means, means for generating output image from said detecting means in which the output images are generated from said reflected energy and form a pair of stereopically related images.
Claim 7
Dependent Claim
83 words
A three-dimensional display system comprising a pair of means for generating beams of energy, means for raster scanning of an object with each of said beams, means for detecting said beams of energy reflected from said object with the reflected beam from one generating means segregated from the reflected beam from the other generating means, means for generating output image from said detecting means in which the output images are generated from said reflected energy and form a pair of stereopically related images.
Claim 8
Dependent Claim
32 words
A system as set forth in claim 5 wherein said means for detecting said beams of energy include means for segregating said reflected beams one from the other on a time basis.
Claim 9
Dependent Claim
54 words
A system as set forth in claim 6 wherein said pair of means for generating energy includes a pair of means for generating a pair of beams in the visual light frequency spectrum, and said means for segregating includes means for selectively actuating one or the other of said pair of energy generating means.
Claim 10
Dependent Claim
33 words
A system as set forth in claim 5 wherein said means for detecting said beams of energy include means for segregating said reflected beams, one from the other on an energy level basis.
