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.

Fahrenheit 451

As announced in entry about Wild Palms, this one would like to introduce an earlier idea of futuristic TV virtual-reality using the example of dystopian science-fiction movie Fahrenheit 451 from 1966 by director François Truffaut, which is based on same-titled novel by Ray Bradbury from 1953. The title referes to the temperature at which paper catches fire. 451 degrees Fahrenheit is about 233 degrees Celsius.

Guy Montag is a fireman. But unlike an usual fireman, his job is not to fight fire, but to burn books, which are forbidden in the story. He is married to Linda, who is prosperous by consuming meds and TV shows. Montag gets to know young teacher Clarisse and falls in love with her. She is not allowed to teach any longer, because she is a passionate books reader. Montag becomes curious and starts reading books secretly.



Fahrenheit 451 (1966)

Like the snippets taken from Wild Palms, this one also shows a futuristic vision of TV virtual-reality. But with a significant difference. While in Wild Palms a holographic projection right in the living room provides the illusion of being part of the TV show, Fahrenheit 451 contents itself with a set of two-dimensional parlor wall screens, for giving the illusion of having your own family around you.

Fahrenheit 451 is brought to the cinemas three years after Emmett Leith and Yuri Upatnieks generate the first three dimensional image. So the idea of projecting a virtual image right into the air can be assumed as known. But it isn't used in Fahrenheit 451 even it would have been a good opportunity and would have made sense to do. This could of course be because of production reasons, for it could last several months or even years to produce a movie, or for it is just to expensive. Despite it is astonishing that it lasts another ten years until holography finds its way to movie. In 1976 one the first holographic images in a movie is used in Logan's Run. Even it is not used to generate a virtual-reality as it is done in Wild Palms to give the illusion of being part of another reality. It seems that Fahrenheit 451 can be read as an example of phantasms and ideas reaching conscious with a delay. Further questions result from this observation: Why does it last more than ten years until holography conquers phantasm space of movie? And when is it first used to generate a virtual-reality that can be felt, touched and experienced?
