Abstract

The analysis of light propagation in a tapered gradient-index (GRIN) medium when the input signal is a binary function is considered with the Walsh–Hadamard analysis. The study of the evolution of the sequency spectrum through the GRIN medium by the Walsh–Hadamard transform confirms the self-imaging effect.
