The results of a study of four different hardened gelatin holographic recording materials are reported. These are the dichromated, diazo, diazo resin, and silver halide (sensitized) gelatins. The report concludes that of the four photosensitive processes studied, the silver halide (sensitized) gelatin process offers the most promising process characteristics. The silver halide gelatin process is a new holographic recording process that can be used toprepare phase volume holograms in hardened gelatin. The process uses a reversal bleach that dissolves the developed silver metal image while further crosslinking the gelatin in the vicinity of the silver image. Upon fixing and with dehydration of the resulting gelatin hologram, one obtains recordings similar to those produced by the dichromated gelatin process. This is accomplish with exposures on the order of 200 to 500 micron J/sq cm at 514.5 nm in a silver halide emulsion that has a panchromatic response. Furthermore, because the hologram has no silver halide present, the holgoram does not exhibit the printout phenomena characteristic of bleached holograms. (Author).

Silver-Halide Recording Materials gives a detailed analysis of the theory, the characteristics, the manufacturing, and the processing methods of silver-halide materials used for the recording of holograms. Emphasis is placed on the selection of suitable silver-halide materials for conventional as well as special holographic applications. A detailed account of current developing and bleaching methods used in the production of silver-halide holograms is given. The author also supplies a large number of recipes for different types of processing baths. The text is complemented by a comprehensive list of references which will facilitate further study. The monograph will be suitable for courses in holography, where the student possesses some background knowledge about the general holographic process and the holographic technique.
