It is notable that all three groups relate to the basic use of the process rather than specific holographic techniques.
You won't see these artists blogging about the private corporate gigs they take for $10 million a pop so they can afford to bring the high-tech, holographic stage rig they desire on their next tour.
Polo Ralph Lauren held a spectacular Manhattan-style garden party in Central Park, with golf buggies ferrying guests to fountain-side champagne bars, and a 4D catwalk show that projected holographic images of the Polo collection above the lake, with the Manhattan skyline behind.
They dispense with "holographic avatars" and "motion-stabilised automated helicopters" early in the book, focusing instead on how technology will affect power structures.
InPhase is testing its first holographic disc-drive, called the Tapestry 900, in conjunction with partners such as Ikegami Tsushinki, a Japanese firm which makes video cameras for the television industry.
This will enable the first holographic discs to store a colossal 300 gigabytes of data 12 times more than the latest Blu-ray discs and 60 times more than a standard DVD.
Digital information is stored in a holographic material in much the same way that pictures are stored in traditional holograms.
Since light takes different paths in material of different densities, such patterns can form optical gratings that change sufficiently fast to create moving holograms.As light passes through such a grating it is diffracted into a horizontal fan, forming a holographic line that is equivalent to one line of a television display.
Storing arbitrary digital information (as opposed to images) in a holographic memory is not easy.
Since the mid-1990s, the laboratory has been at the centre of a consortium to develop holographic storage.
Then this is applied to the holographic memory, which contains transformed target images, each written into the memory using a different reference beam.
