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.
当输入信号为二元函数时，利用沃尔什 - 哈达玛分析来考虑锥形梯度折射率（GRIN）介质中的光传播分析。通过沃尔什 - 哈达玛变换对通过GRIN介质的序列谱演化进行的研究证实了自成像效应。
