Abstract

In the industrial applications of holography as well as in display holography, there is a need to adapt, in order to generate the specifically asked for effect, the type of the recording material or the processing of the emulsion after recording. Therefore, the search for new holographic materials as well as newly adapted processing techniques can lead to easier measurements or to better performances. This paper deals with a description of the techniques used for performance improvement of silver halide photographic emulsions. The study has shown that by the use of a fitted physical developer, the bandwidth of reflection holograms can be increased from 70 nm to 200 nm and diffraction efficiency can reach 14%. Using physical and chemical developments, the color of the hologram can be chosen depending on the composition of the development baths. Values of the efficiency of more than 40% were reported with selected chemical developers.
