Sean Johnston's Top Five Holograms (Real and Imagined)
1 "The toy railway engine", by Emmett Leith and Juris Upatnieks, 1964.
The first publicly exhibited hologram. This image, illuminated by a laser and peered at by hundreds of physicists, inspired an explosion of interest in the subject.
2 "The Kiss", by Lloyd Cross, 1973.
A cylindrical rainbow hologram viewable with a regular light bulb and which, when rotated, shows an animated three-dimensional image of a woman inside blowing a kiss. More risqué holograms were to follow...
3 "National Geographic" March 1984 cover of a Bald Eagle.
This was the first widely available hologram, appearing on millions of magazine covers. It was a reflecting hologram made by embossing a film of aluminium-coated mylar, and was the precursor of the millions of shifting-colour, distorted holograms that most people have seen since.
4 Late 1980s credit card holograms
The ubiquitous glittering images we all carry with us now. There are thousands of more stunning holograms created by artists around the world, but few have achieved fame outside galleries with carefully positioned lighting.
5 The Red Dwarf holograms, 23rd Century.
Vastly superior products indeed! Of course holograms in Red Dwarf are as much a computer product as an optical effect - far more than the real-world holograms above.
