There are two ways for an audience to view 3-D images.
- Each member of the audience sees a different image with each eye. This is called stereoscopic 3-D. The image seen by the left eye is slightly different from that seen by the right eye. The two images are of the same scene as seen from slightly different viewing positions, just as both eyes would see them in life. A viewer’s brain merges the images and tells the viewer that the scene is 3-dimensional. Usually, each of the two images is directed to each eye with special glasses. But, glasses are not always required. In any event, stereoscopic 3-D does not look completely real, and stereoscopic 3-D causes eye strain and headaches.
- Rather than looking at an image, an active screen directs light waves into the eyes of the audience that are the same light waves as if the image really exists. This is how a viewer looks at a hologram. A hologram is not a photograph of an object or a scene. Instead, it filters light so that a viewer sees the light waves generated by the object or scene itself. In this way, a viewer cannot perform any visual test to determine whether the objects in the scene are real. A viewer can look around objects to see what is behind just as in real life. This recreates a scene with stark reality. There is no eye strain because the audience views the scene naturally.
Prior to the invention of the Quantum Optics HolophotoTM Process, it was a well-known limitation that true 3-dimensional images could not be magnified uniformly in all dimensions. The scene would appear distorted in depth. Therefore, any attempt to magnify holograms to show 3-D images on a large screen was not feasible. This explains why holographic movies only exist in science fiction. The basic principle of the Quantum Optics HolophotoTM Process provides uniform magnification of 3-D images produced by holograms or integral photographs. Production of magnified realistic natural 3-D images on large screens that do not require special glasses is now possible.
