Abstract

Two-dimensional color pictures have been recorded as diffractive surface-relief structures in a transparent medium. They are read-out in the zero diffraction order using commercially available slide projectors or microfilm viewers. Compared to conventional color film they offer a considerable cost advantage, as they can be mass produced by hot embossing into thermoplastic sheet. Resolution up to 300 lines/mm is achieved. The pictures contain no dyes and thus cannot bleach with time or on read-out. A color picture is formed by three separate embossings sandwiched together in registration. A black and white picture requires only a single embossing.
