Hologram
Holography is a technique to record the light field, and reconstruction, when the original field no longer exists. It is similar to recording where the sound field is in such a way that it can later be copied code.
Although often called three-dimensional holographic photography, this is a misunderstanding. Photo representatives, hologram, light the scene when appropriate a single fixed image, re-created scenes from the original to light, which can be from different distances, just like in the original scene at different viewing orientations. Hologram itself is a very good random mode, which does not seem to take it the relationship between recorded scenes.
To record the hologram, from an object or a group of objects scattered, some of the light falls on the recording medium. The second light beam, known as the reference light, and illuminated the recording medium, so that interference between the two beams. The resulting intensity of the radiation field is different from that in the holographic recording seemingly random pattern. The right of the map is part of the hologram pictures – the object is a toy car. This photo is from the backlight and the diffuse light hologram, and the focus of the board.
