4. Some hologram properties

The interception by the eye or other light-sensitive receptor of a small portion of the wave scattered by an object enables that object to be seen. We have seen that a hologram reproduces a light wave similar to the one scattered by the object during recording. By intercepting a portion of this wave with the eye, we find ourselves in exactly the same situation as in reality: everything happens, when rendered, as if the object were present. All the usual properties of viewing a scene are respected.

4.1 Parallax

The object scatters the light it receives throughout space and, in particular, onto the photosensitive medium. A small portion A of the hologram thus records information on the whole object as seen from A. Similarly, another portion B will see the entire...
