Paper Abstract

Natural full color holographic images can be perceived by the viewer by superimposing red, green, and blue images simultaneously. This is simplest with single stage reflection holograms and has been successfully accomplished by a number of workers using a variety of techniques on single emulsion or by `sandwiching' red and green/blue sensitive emulsions together. Alternatively using `rainbow' techniques has resulted in good natural color holograms and controlled swellings of a single emulsion has produced spectacular pseudo-color holograms. It would be advantageous to have a single emulsion, of broadband sensitivity, capable of recording color holograms. Such an emulsion, from Russia, was used initially at the University of Aberdeen to create color holograms with good results. Investigations were then carried out on emulsions commercially available in the UK to see if any were suitable for color holography, using single layers. It is shown that a near natural color image can be obtained from a single stage reflection hologram recorded on Agfa 8E75HD film, with no preparation, due to it being sensitive to green and blue wavelengths, as well as to red for which it is normally associated.
