HOLOGRAM Hologram is the recording of an interference pattern which uses diffraction to reproduce 3D light field, which resulting in an image. The image has the depth, the parallax, and the other properties of the original scene. The science and practice of making the holograms is Holography. Photographic recording of a light field, which is rather than an image formed by lens is Hologram. A holographic medium, for example an object produced by the process called holographic process (which may be referred to as a hologram) is usually indiscernible which viewed under a diffuse ambient light. It is an encoding of light field as an intrusion pattern of variations in the opacity, density, or in the surface profile of the photographic medium. That is, the view of an image from different angles represents the subject viewed from similar angles. In this sense, holograms do not have just the illusion of depth but they are three- dimensional images. Looking for Hologram companies in Dubai? Holography which is in its pure form needs a laser light which is used for illuminating subject and for viewing the finished hologram. A microscopic level of the detail throughout the recorded scene can be reproduced. Image quality is made up to remove the need for laser illumination to view the hologram, and in some cases, to make it. Nowadays holograms can also be entirely computer-generated in order to show the objects or the scenes that never existed. Holography is different from other earlier auto stereoscopic 3D display technologies, can produce seemingly similar results but are based on the conventional lens imaging. Images requiring the help of special glasses or any other intermediate optics, the stage illusions such as Pepper's Ghost and any other unusual, baffling, or apparently magical images are often incorrectly called as holograms. Dennis Gabor invented holography in 1947 and later he won a Nobel Prize for his efforts. Several types of holograms can be made. Transmission holograms These discoveries are made by Leith and Upatnieks that are viewed by shining laser light through them and looking at reconstructed image from the side of hologram which is opposite to the source. A later
refinement, the "rainbow transmission" hologram, allows more convenient illumination by white light rather than by the lasers. Rainbow holograms are commonly used for Security Authentication For example, on credit cards and product packaging. Reflection hologram Another kind of common hologram is the reflection or Denisyuk hologram. These can be viewed using a white-light illumination source on the same side of the hologram as the viewer and is the type of hologram normally seen in holographic displays. They are also capable of multicolor-image reproduction. Mostly holograms produced are of static objects but systems which are for displaying changing scenes on a holographic volumetric display are now being developed. Holograms can also be used to store, retrieve, and process the information optically. Today, holograms with x-rays are generated by using the synchrotrons or x-ray free-electron lasers as radiation sources and pixelated detectors such as CCDs as recording medium. The reconstruction is then retrieved via computation. Due to the shorter wavelength of x-rays compared to the visible light, this approach allows imaging objects with higher spatial resolution. As the free-electron lasers can provide ultrashort and x-ray pulses in the range of femtoseconds which are intense and coherent. X-ray holography has been used to capture the ultrafast dynamic processes.
