Optical propagation of fractal fields. Experimental analysis in a single display

An experimental device to show in a single display all the diffraction patterns generated by a 1D fractal structure is proposed. It is found that in addition to being the optimum display to see the evolution of the di? racted ? eld through free space, some interesting features, such as continuous evaluation of self-similarity from the object to the far ? eld, can be obtained experimentally.
