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.

Logan's Run

For it is mentioned in a recent entry, the opportunity should be taken to introduce Logan's Run from 1976. The science fiction movie is based on the same-titled novel by William F. Nolan and George Clayton Johnson in 1967 and is an example for an early use of a hologram in a movie.

In the 23rd century people live in a seemingly paradise trapped under a glass dome, not knowing what is outside. Apparently there is no way out. Under drugs and hallucinogen living a life of sexual laxity most people are not interested of gettig out and knowing what is going on in the outside world. Almost everyone believes in a ritual called renewal, sort of a reincarnation. No one is allowed getting older than 30. A lifeclock - a crystalline device, which changes its colour as a person ages - is implanted in the palm of everyones hand. When on a person's 30th birthday the crystal starts to blink and finally gets black, everyone has to visit the Carousle, which promises a reincarnation on a higher plane of consciousness. But in fact they get killed. There's a legend that there is a place outside the glass dome called Sanctuary. But no one really knows. Few people philosophize about Sanctuary in hidden places and try to escape. These called Runners are haunted by Sandmans of which Logan 5 is one. His job is to find Sanctuary - for it exist - and destroy. He contacts a group of Runners. To make his identiy more credible, his lifeclock is set ahead to his 30th birthday. Logan 5 gets to know Jessica 6 who gets him access to a secret Runner's meeting. But instead of executing her, he helps her to escape. Together the find savaged places where Sanctuary is expected. They meet a very old man far beyond the age 30 and they destroy roboter BOX which froze thousands of other Runners. They realize that the age limit of their society is arbitrary to avoid over population within the glass dome. Returning to tell the people what they found out, they get caught by other Sandmans. Logan 5 is getting interrogated. For his testimony that there is just ruins and wilderness where Sanctuary is expected and that BOX froze thousands of Runners contradicts the calculations of the computer that watches all over the glass dome, it stars its automatic self-destruction.

The attached snippet shows the scene of Logan 5's interrogation.


Logan's Run (1976)

During the interrogation Logan 5's brain is separated into six pieces. Each facsimile acts independently of each other and answers individual questions.

This revolutionary screen technique is seen as a forerunner of the movies and TV entertainment of the future.

Actor Michael York (Logan 5) becomes the first film star performing a hologram.

In 1977 Logan's Run is awarded with the Oscar Special Achievement Award for best visual effects.
