The problem of gray scale image matching based on similitude measurement was discussed. Using an incoherent optical correlator and a shift encoding method, the processing of gray sclae image matching based on similitude measurement was realized. The selection of the length of shift encoding for different distortion in gray level object recognition was analyzed, The optical experimental results were given.
