Abstract
Abstract A microfiche having one surface embossed or molded to define a multiplicity of small lenses (lensettes) integral with the microfiche. Each micro-image is stored directly below a corresponding lensette, thereby assuring optical distance registry between each micro-image and its projection. Lateral optical registry is also realized. In an embodiment, interlensette surface of the microfiche is made opaque to preclude optical cross-talk.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A microfiche adapted for use on a micro optical viewer, said microfiche including: a. a transparent sheet, b. said sheet carrying stored micro optical information distributed over its area, c. one surface of said sheet including a plurality of optically active elements each of which is adapted to function as a lens, said elements being spaced parallel from said stored information, d. said micro optical information defined by a plurality of information sets, each information set corresponding to a unique macro scene, each information set occupying dispersed areas interlaced with but distinct from the dispersed areas occupied by any other information set, each unique macro scene corresponding to a unique set of said active elements, each of the dispersed areas of an information set having its own active element and being in optical correspondence therewith.
Claim 2
Dependent Claim
135 words
A microfiche adapted for use on a micro optical viewer, said microfiche including: a. a transparent sheet, b. said sheet carrying stored micro optical information distributed over its area, c. one surface of said sheet including a plurality of optically active elements each of which is adapted to function as a lens, said elements being spaced parallel from said stored information, d. said micro optical information defined by a plurality of information sets, each information set corresponding to a unique macro scene, each information set occupying dispersed areas interlaced with but distinct from the dispersed areas occupied by any other information set, each unique macro scene corresponding to a unique set of said active elements, each of the dispersed areas of an information set having its own active element and being in optical correspondence therewith.
Claim 3
Dependent Claim
29 words
The microfiche of claim 1 wherein each of the distributed areas on which the micro optical information is stored lies on a corresponding integral nodule having a Petzval surface.
Claim 4
Dependent Claim
25 words
The microfiche of claim 1 wherein said micro optical information is carried by a photographically fixed emulsion carried by one surface of said transparent sheet.
Claim 5
Dependent Claim
14 words
The microfiche of claim 1 wherein those areas between said active elements are opaque.
Claim 6
Dependent Claim
16 words
The microfiche of claim 4 wherein said active elements lie below the surface of said sheet.
