With the invention of laser technology in 1947 by scientist Dennis Gabor. For a short time developed the idea of creating a hologramic image. This name comes from the Greek word HOLOGRAM, – holos (whole) and gramma (message). In practice is photographic projection (technical demonstration) showing three-dimensional image in a space. This holographic image is formed from multiple lights in one place. The holographic image we can seen by looking into an illuminated holographic print or by shining a laser through a hologram and projecting the image on a screen. Actually a hologramic image is produced by mixing more flashing lasers. Holographic image can be displayed as a light print with using laser light or with projecting the image onto a screen from electric appliance.
This is the only picture in the space where we can see from all sides. With this image we can much easier and more visible to consider the details of the case which gives in space. Because of this hologram it is very practical and can be used for various purposes. Hologram would usually used for easier handling and control some electrical devices, display and explanation of various items, fixtures and so on. For example, in medicine, technology, mechanical engineering, cinema, university, scientific laboratories and so on.
