Over the course of its 60-year history, holography has enabled new insights into the nature of light and has contributed to innovative applications, including many unrelated to optics introduction to holography explains how to use holographic techniques to solve specific problems in a variety of fields the text focuses on the. Introduction to holography video by thomas g smith (1972) holography is based on the principle of interference a hologram captures the interference pattern between two or more beams of coherent light (ie laser light) one beam is shone directly on the recording medium and acts as a reference to the light scattered. Looking back at the introduction and application of digital computers to holography, it should be noted that its history did not start only by applying digital computers to simulate the optical recording process it began by the introduction of new ideas which had no direct connection to, and no counter- part in, optical holography. Keywords: holography holographer history sociology technology technological evolution profession discipline 1 introduction – why a history of holography, and why now holography is now slightly over half a century old, if we mark its birth from the first work of dennis gabor, or over four decades old. If a 2d picture is worth a thousand words, then a 3d image is worth a million with holography, it is possible to reconstruct 3d images using holograms, and the process is unlike anything found in traditional display technology even though it was invented over 70 years ago, holography remains the best. Topics include a brief introduction to the history, types, and materials of holography the basic principles of analog and digital holography a detailed explanation of famous fringe-deciphering techniques for holographic interferometry holographic and non-holographic 3d display technologies and. I introduction in recent history of visual multimedia, there has been a rapid development of three-dimensional data content cap- ture and display the main areas of development include stereo- scopic and autostereoscopic systems, head mounted displays, integral photography and digital holography , [2. Computer generated holograms: an historical review g tricoles since gabor's first hologram, the meanings of that term have grown with increased use of the invention computers expanded applications further, and this paper surveys the methods and techniques of computer generated holograms 1 introduction.
4 holography 21 4 holography 41 introduction - history both in maxillofacial reconstructive surgery [ho-in1] as in forensic soft tissue measurements, there is a strong need for a contact-free, optical measurement system this requires a system with a good optical resolution and a short measuring time chen [ho-in2] made. Holograms a cultural history sean f johnston unique topic of popular engagement with holograms offers explanatory, critical and ancyclopeadic content, making it accessible to a variety of readers conitinuous refocusing of narrative to novel social environments and cultural expressions provides analytical coverage. Holography is the science and practice of making holograms typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate.

Been told and retold, mutated and disseminated for different audiences, for nearly sixty years this paper examines some of those perspectives and the disputes, careers and forecasts they inﬂuenced 1 introduction nearly four years ago, i presented a paper at the 17th conference on practical holography. Holographic visions a history of new science sean johnston the first and only book-length history of holography covers the full history of the subject up to the present day in meticulous detail, based on unprecedented archival research and interviews with pioneering holographers based on research supported by the.
In some cases they've been reserved for the esoteric mystery schools, as in judaic kabbalah or the secretive priesthoods of ancient egypt, in other cases we see fractal-holographic principles permeate an entire religion, which is especially pronounced in the wisdom traditions of vedic and chinese origin, such as buddhism. Introduction ray-tracing is a convenient way to model optical systems using a computer computer-generate holograms (cghs) potentially offer a new, valuable generation of holograms for 2d and 3d object models and reconstruction of their virtual tricoles,g computer generated holography: an historical review.

Origins of holography application areas styles of analysis references chapter 2: light as waves light wave shapes light as repetitive waves light as sinusoidal waves coherence in waves e&m nature of the waves intensity ( irradiance) conclusions references chapter 3: waves and phases introduction. A personal history probably the first lenticulars i was aware of were 'winky postcards', which as a prepubescent boy, caught my eye on the racks outside tobacconists when on holiday in italy and france in the 1960s i still have one bought in cannes which came with quite a strong perfume embedded in it on the back it.
History of holography the development of hologram technology started in 1962, when yuri denisyuk, in the soviet union, and emmett leith and juris upatnieks at the university of michigan developed laser technology that recorded 3d objects silver halide photographic emulsions were used for the. Goodman finished his doctorate just as the cw laser became commercially available and as a new era of holography and optical information processing was opened by he is the author of the introduction to fourier optics (now in its 3rd edition), statistical optics, speckle phenomena in optics, and co-author of fourier. Holography: holography, means of creating a unique photographic image without the use of a lens the photographic recording of the image is called a hologram, which appears to be an unrecognizable pattern of stripes and whorls but which—when illuminated by coherent light, as by a laser beam—organizes the light.
