Leith actualized (made visible) Gabor’s mathematical holographic procedure, but other striking examples of this process are visible to us in nature every day. A holographic process is nothing more than an interference pattern created by the interaction of two or more waves. For example, if you throw a pebble into a pond, a series of concentric circles—waves—will expand outward. If you drop two pebbles side-by-side, two sets of waves will expand until they intersect. At the point where the circles of waves cross, they reinforce or diminish each other, creating what we call an interference pattern. A remarkable aspect of these interference patterns is that the information of exactly when and where the pebbles hit the pond is spread throughout the surface of the water—and that the place and moment that the pebbles had hit the pond can be reconstructed from the pattern. We accomplish this by simply reversing the process: if we filmed it, we run the film backward; or, if we used Gabor’s mathematics, we simply invert the transformation. Thus, the location and time of the point of origin can always be recovered from the interference pattern.
