ABSTRACT
Holography is a unique method of producing three-dimensional images. It did not evolve from photography, but from a number of ideas associated with electron micrography and radar, and it was developed not by artists or photographers, but by physicists. Consequently, many people don’t associate holography with creative image making, and think you need a PhD and a laboratory full of expensive equipment before you can think about making a hologram. In fact, anyone can make a hologram in a cupboard under the stairs with no more equipment than a glass plate, a laser pointer from a souvenir shop, a piece of holographic film, and some processing chemicals. You don’t even need a lens. Holography produces its images by using the principle of optical interference, which we first met in Chapter 1.
