In the foregoing example, the pebbles represent energy in motion while the water(before its agitation by the pebbles) represents energy at a state of rest. ![]() The key to creating any hologram is that energy in motion must interact with energy in a state of rest(nonmotion). ![]() The smaller the piece, the fuzzier and more distorted would be the resulting holographic projection but the fact remains that a whole projection would nonetheless be made. Of further importance is the fact that even if we dropped our frozen hologram of the ripple pattern on the floor and broke it into a number of pieces each individual piece would recreate the entire holographic image all by itself. ![]() The record will be a hologram of the face."ฤก3. And if one of the beams, instead of coming directly from the laser, is reflected first off an object such as a human face, the resulting pattern will be very complex indeed, but it can still be recorded. When two laser beams touch, they produce an interference pattern of light and dark ripples that can be recorded on a photographic plate. ![]() "The purest kind of light available to us is that produced by a laser, which sends out a beam in which all the waves are of one frequency, like those made by an ideal pebble in a perfect pond.
