Holographic analogues

Holographic reconstruction of images as a simulation of actual boundary con ditions for the reconstructed wave is commented in connection with the poss ibility of simulation of other phenomena. When some non wavelike phenomena are simulated by reproducing the boundary conditions in a region some physi cal magnitude is reconstructed in a way that is very similar to that obtain ed in holography. The analogy can be used to generate new insights in the s imulated phenomena.
