Holography is considered as one of the most remarkable discoveries in modern times. Nevertheless for its first decades it seems to be getting forgotten.

Originally stepped up back at the end of the 1940s to improve electron microscopy, it can not fulfill this function and the wish of its discoverer hungarian-british physicist Dennis Gábor. Due to sources of pure coherent light, which are indispensable for optical holography, being not yet available, not even Gábor himself can locate a field of application for this phenomenon. He can neither recognize at that point of time the meaning and the potential of his discovery and with it the influence this new medium would have on our daily lives one day. Nor can he imagine the plenty of phantasms emerging from this phenomenen. Phantasms, which seem to be mostly one step ahead of applied holography.

With the discovery of laser light at the beginning of the 1960s, for the first time ever it becomes possible to record and reconstruct a real three-dimensional image of an object. What once simply starts as a little rainbow coloured picture of a toy train, today finds its applications in a vast variety of different optical and acoustical fields.

It is as remarkable as the phenomenon of holography itself, that it could never prevail as a popular medium like movie, TV, radio, the internet, print media, etc. Especially when keeping in mind all the phantasmatic stories which emerge from this medium. A lot of dreams, hopes and promises that holography never made by itself, but some of them is trying to keep.

blog.holographie.eu accompanies my scientific work on holography, which would like to give holography an attention, that elsewhere is mostly refused to it. It is of course initially interested in based techniques and technologies of holography and how it works. Moreover it is also interested in these upcoming phantasms and their stories arising from possible abilities of holography. Especially against the backdrop of holography seems to be reaching a point, where its possibilities and abilities catch phantasms.

This blog would like to serve as a sketch book for unprotected ideas, of which some maybe become expanded, while others are not haunted any further, but wants to be told and should not be unmentioned forgotten.

5th June: 110th birthday of Dennis Gábor

Due to a lot of work on the issue of holography, Dennis Gábor's birthday completely slipped this blog's mind. Even a tad too late, this should not stay unmentioned.


Born 5th June 1900 in Budapest as a son of jewish parents, Dennis Gábor (hung. Gábor Dénes) passes a study of electrical engineering at Budapesti Műszaki és Gazdaságtudományi Egyetem (TUB) in 1920, that he continues from 1921-1924 at Technische Hochschule in Berlin Charlottenburg. Three years later he takes a doctoral degree - thesis: Oszillographieren von Wanderwellen mit dem Kathodenoszillographen. After getting his PhD, Gábor works at Siemens & Halske AG on his invention of high pressure mercury quartz lamp. Because of his jewish roots, in 1933 he emigrates to England, where he gets the british citizenship and works for Thomson-Houston. 1947/1948 he discovers the principle of holography - at that time called wavefront reconstruction. In 1949 he joins the Imperial Collage of Science & Technology in London. First as a reader of Electronics, later as a Professor of Applied Electron Physics, where is stays until his retirement in 1967. He stays connected as a Senior Research Fellow and becomes a Staff Scientist at CBS Laboratories, where he collaborates with his life-long friend Dr. Peter C. Goldmark in new schemes of communication and display.

Since 1958 Gábor spends much time on a new interest of his: the future of our industrial civilization. His conviction "[...] that a serious mismatch has developed between technology and our social institutions and that inventive minds ought to consider social inventions as their first priority [...]" finds its expression in is three books: Inventing the future (1963), Innovations (1970), and The mature society (1972).

In 1971 Dennis Gábor gets honoured with the Nobel Price in Physics for his invention and development of the holographic method.

8th February 1979 he dies in London.


"You can't predict the future, but you can invent it." (Dennis Gábor)
