Are they serious? It's NOT A HOLOGRAM!

[Anomalocaris]

The same thing was done last year for ITV's Les Dawson: An Audience With That Never Was to bring the man himself to life. That too was touted as a hologram. I agree with Aractus that the use of the term 'hologram' is inaccurate and misleading. It's on the lines of selling those old comicbook advertised "X-ray specs" as genuine medical and surveillance equipment. A hologram is an interference pattern in a medium such as film generated by the arrival time difference at the medium's surface between two coherent laser beams, one reflected off a target object and the other a reference beam. Sufficient information is recorded to exhibit parallax, giving a realistic three-dimensional photographic image of the object viewable from various angles. The technique used for these stage presentations is an updated form of Pepper's Ghost and predates holography as we know it by over three centuries. The technology involved in creating the modern iteration of the illusion is undoubtedly impressive, but not holography.

Not quite. A holographic image is one which captures all information contained in the light field of the object being examined, including, phase, intensity and frequency of the light field. It is the phase information which allows the image to exhibit proper parallax. How that is achieved, what medium is used, is besides the point. In physics there is referred a holographic principle. It has nothing to do with any laser beams and any interference pattern.

A mirror reflected image meets the basic criteria of a holographic Image, in fact better than most holographic images recorded with laser beams and stored on a medium.

The fact that mirror reflected image existed long before modern methods to store holograms was invented, indeed before the concept of holograph could even have been conceived of, does not change the fact it is a hologram.

If is no different from calling the little spark you get from walking on carpets and then touching door knobs startic electricity even though the spark was produced in this manner long before anyone has heard of static electricity.
