中文摘要	A coherent optical data-processing method based on volume holographic correlator is described, which has the potential for performing Walsh transform at a high processing rate. The input image and stored images of volume holographic correlator are encoded to represent the data vector and Walsh functions in Walsh transform. And the output of volume holographic correlator can represent the result of Walsh transform. An experiment is carried out, and the correspondency of experimental result and theoretical one proves the effectiveness of the method.
