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.

The man who fell to earth

In the same year as Chuck Browning and Tracy Ballard play holo chess in Futureworld, another movie comes to the cinemas using a hologram: The man who fell to earth.

In the Sci-Fi movie from 1976, which is based on same-titled novel by Walter Tevis from 1963 and directed by Nicolas Roeg, David Bowie plays main character Thomas Jerome Newton. Newton is a humanoid alien from outer space falling down to earth to find water for his dried out planet. He founds hi-tech billion company World Enterprise to build a spaceship taking him back home again.

Right in the middle of the movie is a short shot showing his wife on far distant home planet forestalling the idea of holographic television. She holds a holographic screen to watch his husband on earth.



The man who fell to earth (1976)


Therewith The man who fell to earth is also one of the earliest movies, in which holography appears.

The above shown scene does not just show a hologram. Subliminal the scene demonstrates one of the main characteristics of holography, the parallax view. The alien wife can see the front of red-head Newton in the TV commercial, that stays hidden to the observer sitting in front of the TV watching it.

While in Futureworld the chess game is not recognizable as holographic chess and needs later explanation, the holographic display in The man who fell to earth is clearly visible as a hologram, as it is in use.
