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.

3D holographic telecast - Football World Cup 2022 in Japan

Between some more fundamental and technical entries, here comes another phantasm, because of the topical inducement. It is one of a very ambitious effort.

In ten days South Africa and Mexico kick off the Football World Cup 2010 in Johannesburg.

Back in 1954 the Football World Cup has been broadcasted by TV for the very first time. Football fans all over the world witnesses Germany surprisingly winning the championship in front of their radio or black/white television set.
About 50 years later in 2006, it has become very popular either to watch the games at one of the many public viewing events or a new flat-screen TV. This year adds another innovation. German private sports channel sky for the very first time and as the only german TV station broadcasts all 64 games in real HD. There are also plans by FIFA and sony to broadcast up to 25 games in 3D technology in chosen cities. Chances that this is going to be converted are are not that good at the moment due to insufficient quality.

Obviously the ways to watch sports events has changed and developed and with it of course the demands as well. How does a broadcast of sports events look next? According to the current variety and huge success of 3D movies like Avatar, Up, A Christmas Carol, Alice in Wonderland, Toy Story 3, Tron (beginning 2011) - just to name a view - and actual efforts by FIFA and sony, the answer could be: Watching next WC 2014 in Brazil in 3D.

And here is, what it could look like after next:
For the case Japan is chosen by FIFA on 2nd December this year as the host of the 2022 World Cup edition, it promises an ultra-realistic live 3D telecast of the matches. Therefore 200 high-definition cameras should capture the players on the field from 360 degrees. Additional to that microphones should be installed below the bitch for creating an ultra-realistc digital version. This futuristic phantasm should be powered partly by electricity generated by spectators stamping their feet and partly by solar panels.

"You may think that the technologies you see are like something from a science fiction film, but we have several phases and we have 12 years to realize these technologies. We have to develop the technology alongside human being so of course we face a big challange, but we have already finished the research phase and by 2016 we will be able to realize these technologies for use. We are very confident that we will be ready by 2022."
(Jun Murai, professor at University of Keio and director of technology)

The captured images should be transmitted as three-dimensional images and shown on giant screens in about 400 selected stadiums in FIFA's 208 member countries. Or, if technological advances in coming years allow, the images should be projected right onto the pitch, so that some 360 million attendees get the illusion of viewing a real match.

In 2006 estimated about 18 million people attended official public viewing events. "Weenvisage public viewing at stadiums, increasing the attendance by tens of time." (Makato Maruyama, director of operations at the Japan bid committee)

This of course is a really fantastic vision. But it isn't less remarkable, that a completely other technology takes holography as a paragon and mimics it. It pretends to project holographic images, which it does not. One feature of a hologram is, that it provides an image that can be viewed from an infinite possible angle. A 360 degrees image even taken by 200 cameras can not. Anyway how many cameras there are, there is always an angle missing. So this technology does not provide a holistic image. It occurs, that in public and general perception terms like holography or hologram are very close connected with 3D.
