The holographic "image" is not an image at all but a series of
interference patterns which are used to "construct" the image in space
via laser light which is monochromatic and coherent. In order to avoide
distortion the backing is non flexable glass. This will give
the best image.
The plates are sensitive to red laser light and fairly slow. They
are also rather expensive.
When we made holos many years ago we would make them at 2-4 AM when
there we no cars and trucks driving by.
