Abstract
Abstract The invention relates to the production of three dimensional images for direct viewing or for recording on a sensitized recording surface. The invention provides a method and apparatus for the direct production of integral parallax orthoscopic panoramagramic images, which objective is met by a process comprising directing at an object a means of gathering and focussing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means a grouping means for producing a number of groups of individual waves, each group emanating from a part of said object, said grouping means generating an image in pseudoscopic form, and a means of encoding the pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
A method of producing a parallax panoramagramic image in a single stage comprising directing at an object a means for gathering and focusing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means, a grouping means for producing and transmitting a number of groups of individual waves, each group emanating from a part of said object, said grouping means generating an image in pseudoscopic form, and a means for encoding the transmitted pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.
Claim 2
Independent Claim
103 words
A method of producing a parallax panoramagramic image in a single stage comprising directing at an object a means for gathering and focusing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means, a grouping means for producing and transmitting a number of groups of individual waves, each group emanating from a part of said object, said grouping means generating an image in pseudoscopic form, and a means for encoding the transmitted pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.
Claim 3
Dependent Claim
30 words
A method as in claim 1, wherein the incoming radiation is of a wavelength in the visible range and the gathering and focussing means is a single large aperture lens.
Claim 4
Dependent Claim
18 words
A method as in claim 1 or claim 2, wherein said grouping means is an autocollimating transmission screen.
Claim 5
Dependent Claim
22 words
A method as in claim 1 or claim 2, wherein said grouping means is a transmission type double integral fine pitch screen.
Claim 6
Dependent Claim
27 words
A method as in claim 1, wherein the means of encoding the pseudoscopic image as discrete parallactic information on a single plane is an apertured lenticular screen.
Claim 7
Dependent Claim
31 words
A method as in claim 1, wherein the means of encoding the pseudoscopic image as discrete parallactic information on a single plane is a lensed screen capable of producing integral images.
Claim 8
Dependent Claim
90 words
An imaging system for producing a parallax panoramagramic image in a single stage comprising a means for gathering and focussing incoming radiation from an object, there being positioned to either side of said gathering and focussing means a grouping means for producing and transmitting a number of groups of individual waves, each group emanating from a part of said object and there being a means of encoding a pseudoscopic image generated by said grouping means as discrete parallactic information on a single plane for subsequent viewing as an orthoscopic image.
Claim 9
Dependent Claim
90 words
An imaging system for producing a parallax panoramagramic image in a single stage comprising a means for gathering and focussing incoming radiation from an object, there being positioned to either side of said gathering and focussing means a grouping means for producing and transmitting a number of groups of individual waves, each group emanating from a part of said object and there being a means of encoding a pseudoscopic image generated by said grouping means as discrete parallactic information on a single plane for subsequent viewing as an orthoscopic image.
Claim 10
Dependent Claim
50 words
An imaging system as claimed in claim 7, wherein said apparatus is a camera comprising a wide aperture lens, an autocollimating transmission screen, and a lenticular or lensed screen, and whereby an encoded pseudoscopic image is projected as discrete parallactic information directly on to the focal plane of said camera.
Claim 11
Dependent Claim
53 words
An imaging system as in claim 7, when the incoming radiation is X-rays, comprising a perforated X-ray barrier, a phosphorescent screen to convert said X-rays to visible radiation, an integral lens array to group said radiation, and a means of encoding as discrete parallactic information a pseudoscopic image generated by said grouping means.
Claim 12
Dependent Claim
26 words
