Filed Jan, 15,1968. Published Apr. 15, 1969 Class 96-27 1 Sheet Drawing. 13 Pages Specification The manufacture of a hologram which is viewable in white light by a photographic printing method is disclosed. In the first step of theijmethod, a master hologram of a. conventional typefis placed in close contact with an unexposed photographic emulsion, which is the top layer of a multilayer structure. Alternatively, instead of a hologram, an article referred to as a holocoder may be placed in contact with the emulsion. The emulsion is the top layer of a structure including a rigid base having a smooth upper surface which is coated with a thin layer of gelatin and a thin layer of metallic silver. The multilayer structure is exposed through the hologram lby monochromatic light or by light emitted from a laser.
The light is spatially modulated by the hologram and then reflected by the silver layer which functions as a mirror, thereby forming spatially modulated standing waves in the unexposed emulsion,
In the next step, the hologram is removed and the re maining layers of the article are developed and fixed, The multilayer structure is then bleached so'that the metallic silver in both the emulsion and the silver layer is converted into silver bromide, which is then re-exposed to the laser light or the monochromatic light and re-developed, As a result, there is opaque granular silver both in the exposed area of the emulsions and in the silver layer which previously functioned as a mirror, The article thus pro= duced is a hologram which can be viewed in white lighta
