   thumb|two photographs of a single hologram taken from different viewpoints holography is a technique which enables three-dimensional images (holograms) to be made. it involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording. the image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the image appear three-dimensional. the holographic recording itself is not an image; it consists of an apparently random structure of either varying intensity, density or profile. ==overview and history== the hungarian-british physicist dennis gabor (in hungarian: gÃ¡bor dÃ©nes),gabor, dennis. (1948), a new microscopic principle, nature, 161, p 777-8 was awarded the nobel prize in physics in 1971 "for his invention and development of the holographic method". his work, done in the late 1940s, built on pioneering work in the field of x-ray microscopy by other scientists including mieczysÅaw wolfke in 1920 and wl bragg in 1939.hariharan, (1996), section 1.2, p4-5 the discovery was an unexpected result of research into improving electron microscopes at the british thomson-houston (bth) company in rugby, england, and the company filed a patent in december 1947 (patent gb685286). the technique as originally invented is still used in electron microscopy, where it is known as electron holography, but optical holography did not really advance until the development of the laser in 1960. the word holography comes from the greek words  (hÃ³los; "whole") and  (graphá¸; "writing" or "drawing").  the development of the laser enabled the first practical optical holograms that recorded 3d objects to be made in 1962 by yuri denisyuk in the soviet union{{cite journal | title = on the reflection of optical properties of an object in a wave field of light scattered by it | last = denisyu
