fragments of film I read a book called the "Holographic Universe". It explained how a hologram is generated. One aspect of hologram creation holds a puzzle that the book I read did not know the answer to. I have not found the answer anywhere and I am looking for a solution to this puzzle. The puzzle is this: Why is it that any segment of holographic film can produce the image of the entire hologram? I will not go into how a hologram is produced unless it is requested of me to do so...but in the end a laser goes through a two dimensional film that creates the three dimensional image which we call a "hologram". When the entire film is in one piece the image is clear and crisp. Yet, as I wrote, if only a fragment of the film is present for the laser to go through, the entire image, the same image that the whole piece of film creates, is created. The only difference is that when only part of the film is being shot through with a laser, the end image is not as crisp, not as clear, slightly fuzzy. If I remember correctly, to imagine holographic film is to think of looking at a body of water frozen in time that has had the effect of many pebbles tossed into it. On the film there appears circles within circles within circles that interact with with other circles within circles within circles on the film. So my riddle that still remains unsolved is why and/or how does a fragment of this film, have the ability to produce the entire image?
