What is the material that holograms are printed on? HOw do i mAKe one? where do i get that material?

Answer 1

You need a holographic plate of film. Then you bounce a laser off of something. I would forget it.

Answer 2

Holography (from the Greek, Όλος-holos whole + γραφή-graphe writing) is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. The technique of holography can also be used to optically store, retrieve, and process information. It is common to confuse volumetric displays with holograms, particularly in science-fiction works such as Star Trek, Star Wars, Red Dwarf, and Quantum Leap.
The so-called "holograms" appearing in identity documents, credit cards, banknotes or expensive merchandise are not true holograms. Their apparent depth comes from stereoscopy (as in 3D comics). If you turn the "hologram" upside down, the depth of the image is inverted. All depth disappears if you turn the hologram 90° or if you look at it with just an eye. This is not the case with true holograms, which are not based on binocular vision but in the reconstruction of a virtual image. True holograms give the same 3D images when viewed at any angle or with just an eye.
The difference between holography and photography is best understood by considering what a black and white photograph actually is: it is a point-to-point recording of the intensity of light rays that make up an image. Each point on the photograph records just one thing, the intensity (i.e. the square of the amplitude of the electric field) of the light wave that illuminates that particular point. In the case of a colour photograph, slightly more information is recorded (in effect the image is recorded three times viewed through three different colour filters), which allows a limited reconstruction of the wavelength of the light, and thus its colour.

However, the light which makes up a real scene is not only specified by its amplitude and wavelength, but also by its phase. In a photograph, the phase of the light from the original scene is lost. In a hologram, both the amplitude and the phase of the light (usually at one particular wavelength) are recorded. When reconstructed, the resulting light field is identical to that which emanated from the original scene, giving a perfect three-dimensional image (albeit, in most cases, a monochromatic one, though colour holograms are possible).

haha i don't think they print those
