Holography is the scientific technique of making an image using a special light from a LASER. Holograms usually look three-dimensional. This is because, unlike photography that only records the brightness and contrast of an object, a hologram records brightness, contrast and dimension.
You do not need any special glasses to view a hologram. Holograms are used for by companies on packaging for attractive display of their logo and to reduce the chance for forgery.
Some holography techniques are already used in movies and it is possible that in the future all movies will be holographic! It would be like experiencing action as if you were in the film.
Hungarian-British physicist Dennis Gabor was awarded the Nobel Prize in Physics in 1971 for developing the holographic method.
