Silver halide sensitized gelatin (SHSG) holograms are similar to holograms recorded in
dichromated gelatin (DCG), the main recording material for holographic optical elements
(HOE's). The drawback of DCG is its low sensitivity and limited spectral response. Silver
halide materials can be processed in such a way that the final hologram will have properties
like a DCG hologram. Recently this technique has become more interesting since the
introduction of new ultra-high-resolution silver halide emulsions. An optimized processing …

Silver halide sensitized gelatin (SHSG) holograms are similar to holograms recorded in
dichromated gelatin (DCG), the main recording material for holographic optical elements
(HOEs). The drawback of DCG is its low energetic sensitivity and limited spectral response.
Silver halide materials can be processed in such a way that the final hologram will have
properties like a DCG hologram. Recently this technique has become more interesting since
the introduction of new ultra-fine-grain silver halide (AgHal) emulsions. In particular, high …
