APPARAT FOR BETRAKTNING AV MIKROFILMKORT |
| 摘要 |
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. |
