The formula of the diffraction patterns which were made by the grating with the variable periods were derived. The diffraction patterns which had the various data value of the variable periods were simulated by the IBM PC., and the characteristics of the patterns were discussed. The purposes of this study was to find the periods of the real grating and their degree of variation by using the results of the experiment.
