抄録

A generalized phase-shift method is developed for automatic measurement of isochromatic fringe orders in the entire field of a model. This method uses two sets of light intensities obtained from the rotation of polaroids in dark-field and light-field plane polariscopes at each point. In order to investigate the accuracy of the measurement, light intensity curves in time series with different noise and different numbers of data which constitute the curves are used in computer simulation. The accuracy of the fringe orders obtained by the method is hardly affected by noise when the number of data exceeds l00. This method is applied to a circular disk subjected to a concentrated load. As a result, the fringe orders obtained by the method are found to be in good agreement with the theory.
