Abstract
There is described a method of and apparatus for improving the appearance of holographic displays reproduced from picture holograms. The method and apparatus involves the use of a holographic reflection filter (2) through which the hologram-illuminating light is filtered. The holographic reflection filter has a number of narrow passbands each associated with the frequency of the colour or colours to be reproduced by the picture hologram (3). There is described also a method of fabricating the hologram reflection filter.
