True Colour: What Does it Mean for Holography?(Brief Article)

It's been a long time coming, but there is a real feeling that effective and commercial true colour holography is about to make its mark on the holography markets. The level of colour saturation, efficiency and resolution achieved by Laboratoire d'Holographie (see p13) with hand-made emulsions gives the producers of low-cost mass-produced colour holograms something to aim for. The Gentet brothers have raised expectations in colour holography, but having shown what can be achieved, the resources of DuPont, Dai Nippon and others will now have to be focused on delivering that quality in mass-production.

It is difficult to predict the impact on the markets of this quality …
