Abstract
Abstract The invention described and claimed herein is a method and apparatus for producing a picture of an opaque three-dimensional subject in which the picture conveys to the unaided eyes of the observer the true spatial relationship of the internal and external elements of the subject. Specifically, the invention provides for relative rotation between a subject and the combination of a radiation source and plane transducer to produce photographic light that is scanned through a narrow aperture across a displacement grid in front of a film plane. The foregoing produces a photograph that upon direct viewing through the displacement grid conveys full internal well will as external depth perception.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
A process of depth-perception radiography comprising the steps of: a. irradiating a subject with a penetrating radiation that has the intensity thereof affected in passage through the subject; b. transducing radiation emerging from the subject into photographic light emanating from a plane surface and proportional in intensity to incident radiation at a corresponding point on the opposite side of the surface; c. focusing said photographic light from step b through a small aperture upon a photographic medium having a displacement grid on the front surface thereof; d. casting a changing radiation pattern of the subject upon a transducing plane of step b by relatively rotating the subject and the combination of the radiation source and transducer which are fixed with respect to each other; and e. changing the angle of incidence of light on said photographic medium in synchronism with step d, to focus a plurality of images in interleaved portions upon said photographic medium for individual retrieval.
Claim 2
Dependent Claim
158 words
A process of depth-perception radiography comprising the steps of: a. irradiating a subject with a penetrating radiation that has the intensity thereof affected in passage through the subject; b. transducing radiation emerging from the subject into photographic light emanating from a plane surface and proportional in intensity to incident radiation at a corresponding point on the opposite side of the surface; c. focusing said photographic light from step b through a small aperture upon a photographic medium having a displacement grid on the front surface thereof; d. casting a changing radiation pattern of the subject upon a transducing plane of step b by relatively rotating the subject and the combination of the radiation source and transducer which are fixed with respect to each other; and e. changing the angle of incidence of light on said photographic medium in synchronism with step d, to focus a plurality of images in interleaved portions upon said photographic medium for individual retrieval.
Claim 3
Dependent Claim
29 words
The process of claim 1 further defined by said displacement grid having transparent cylindrical lenticulations, and said rotation being about an axis parallel to the axis of said lenticulations.
Claim 4
Dependent Claim
29 words
The process of claim 2 further defined by changing the angle of incident light by laterally moving a narrow, elongated slit aligned parallel to the axes of said lenticulations.
Claim 5
Dependent Claim
23 words
The process of claim 3 further defined by moving said slit aperture across a large objective lens focusing light upon said photographic medium.
Claim 6
Dependent Claim
24 words
The process of claim 3 further defined by moving a small objective lens and said narrow, elongated slit aperture together laterally of said lenticulations.
Claim 7
Dependent Claim
34 words
The process of claim 2 further defined by rotating both said photographic medium and the subject in synchronism while focUsing light on the photographic medium through a narrow elongated slit parallel to said lenticulations.
Claim 8
Dependent Claim
35 words
The process of depth-perception radiography as set forth in claim 1 further defined by continuously changing the radiation pattern of the subject in step d whereby continuously varying images are focused upon said photographic medium.
Claim 9
Dependent Claim
41 words
The process of depth-perception radiography as set forth in claim 1 further defined by changing the radiation pattern of the subject upon the transducer plane in discrete increments in step d whereby successive juxtaposed images are focused upon the photographic medium.
Claim 10
Dependent Claim
125 words
Apparatus for depth-perception radiography comprising: a. a source of penetrating radiation; b. means for mounting a subject in front of said source; c. a transducer disposed on the opposite side of said subject from said source and producing photographable light from incident radiation; d. a photographic medium having a displacement grid on a front face thereof; e. an objective lens focusing light from said transducer on the front face of said photographic medium; f. means maintaining the source and transducer in fixed relation relative to each other and relatively rotating same with respect to said subject; and g. means scanning a narrow aperture across said photographic medium to direct light from different angles thereon to record an image having juxtaposed and separable interleaved image portions.
Claim 11
Dependent Claim
125 words
Apparatus for depth-perception radiography comprising: a. a source of penetrating radiation; b. means for mounting a subject in front of said source; c. a transducer disposed on the opposite side of said subject from said source and producing photographable light from incident radiation; d. a photographic medium having a displacement grid on a front face thereof; e. an objective lens focusing light from said transducer on the front face of said photographic medium; f. means maintaining the source and transducer in fixed relation relative to each other and relatively rotating same with respect to said subject; and g. means scanning a narrow aperture across said photographic medium to direct light from different angles thereon to record an image having juxtaposed and separable interleaved image portions.
Claim 12
Dependent Claim
48 words
The apparatus of claim 9 further defined by said displacement grid comprising cylindrical lenticulations parallel to said slit, and the means of g including a plate with a slit therein and an objective lens over said slit and means moving both plate and lens laterally across said lenticulations.
Claim 13
Dependent Claim
56 words
The apparatus of claim 9 further defined by said displacement grid having parallel transparent lenticulations on a light intercepting face thereof, said relative rotation being provided about an axis parallel to the axis of said lenticulations and said aperture having a width less than that effecting exposure of one-half of the photographic medium behind each lenticulation.
Claim 14
Dependent Claim
63 words
The apparatus of claim 9 further defined by the medium d comprising parallel cylindrical transparent lenticulations upon a light-intercepting face of photographic emulsion, and said narrow aperture having a limited maximum dimension laterally of the lenticulations so that an instantaneous image thereof focused on said emulsion behind each lenticulation has a width limited to a small fraction of the width of the lenticulation.
Claim 15
Dependent Claim
27 words
The apparatus of claim 12 further defined by said narrow aperture being elongated parallel to the axes of lenticulations to maximize light focused on said photographic medium.
Claim 16
Dependent Claim
61 words
The apparatus of claim 9 further defined by the means g including means defining a narrow aperture between said objective lens and said photographic medium and means rotating said photographic medium d and means b mounting a subject in synchronism while maintaining the remainder of the apparatus fixed with respect thereto for directing light from different angles onto said photographic medium.
