Abstract

Abstract An apparatus for use as both a camera and a viewer. As a camera, light from an object is broken up by a planar array of N lenses into N identical images which fall onto an opaque mask. A small aperture lies within each image, but at a different relative zone so that the apertures are non-homologous with respect to the image. Light passing through the apertures strikes virgin photographic emulsion of a lensfiche. The lensfiche is indexed and the process repeated for the next object. After emulsion development, the lensfiche is sequentially illuminated from the rear and each object (macroscene) sequentially reconstructed by projection on a viewing screen. For one embodiment, the method of recording consists of forming N identical and non-overlapping images, taking one portion from each of the N images, the N portions being non-homologous and dispersed from each other, and photographically recording N non-homologous portions. For readout, the N portions are projected and magnified on a screen to reconstitute the original object, the N portions now coalesced to form a coherent, non-dispersed image.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 259 words
A method of recording by photography, including the steps of, (a) simultaneously forming N non-overlapping similar images of an object by permitting light from an object to fall upon N objective lenses of a lens array and allowing the light passing through each of the N lenses to fall on an opaque scene mask which is located at a distance from the lenses substantially equal to their focal length, (b) selecting one portion less, than the whole, from each of the N images, to thereby define N portions, each of the N portions being non-homologous with respect to the image, the N portions being spaced apart from each other so that their borders do not touch each other, by placing N spaced apart apertures in said opaque scene mask, the N apertures each being smaller than each image, each aperture corresponding to a single one of said objective lenses, (c) photographically recording each of the N portions by placing a photographic emulsion on the side of said opaque mask remote from said objective lenses, spaced from but contiguous to said opaque plate, and allowing light passing through the N apertures to fall upon the emulsion to thereby form a distributed set of exposed emulsion areas corresponding to a scene being recorded, (d) step b) being carried out by so arranging the N apertures over the opaque scene mask such that when the distributed set of exposed emulsion areas is projected, after photographic fixing thereof through inverting lenses for readout, a congruent, positive image is formed on a viewing screen.
Claim 2
Independent Claim 259 words
A method of recording by photography, including the steps of, (a) simultaneously forming N non-overlapping similar images of an object by permitting light from an object to fall upon N objective lenses of a lens array and allowing the light passing through each of the N lenses to fall on an opaque scene mask which is located at a distance from the lenses substantially equal to their focal length, (b) selecting one portion less, than the whole, from each of the N images, to thereby define N portions, each of the N portions being non-homologous with respect to the image, the N portions being spaced apart from each other so that their borders do not touch each other, by placing N spaced apart apertures in said opaque scene mask, the N apertures each being smaller than each image, each aperture corresponding to a single one of said objective lenses, (c) photographically recording each of the N portions by placing a photographic emulsion on the side of said opaque mask remote from said objective lenses, spaced from but contiguous to said opaque plate, and allowing light passing through the N apertures to fall upon the emulsion to thereby form a distributed set of exposed emulsion areas corresponding to a scene being recorded, (d) step b) being carried out by so arranging the N apertures over the opaque scene mask such that when the distributed set of exposed emulsion areas is projected, after photographic fixing thereof through inverting lenses for readout, a congruent, positive image is formed on a viewing screen.
Claim 3
Dependent Claim 52 words
The method of recording by photography of claim 1 including the additional step of, (a) preventing optical cross-talk between portions of light passing through the objective lenses and falling upon the opaque scene mask, the step being performed by inserting a plurality of septa between the objective lenses and the scene mask.
