| 摘 要： | 本文用傅里叶光学原理讨论了迭合栅云纹倍增问题,得出了光强随位移连续变化的公式。讨论了相干滤坡系统中试件均匀变形和非均匀变形问题。云纹栅可以是振幅型或位相型或振幅兼位相型的。所得公式具有普遍意义,并和Post的实验符合。

| Abstract: | In this paper, the principle of Fourier optics is used in treating the problem of moir6 fringe multiplication formed by two contact gratings. A continuous relationship between displacement and light intensity is obtained. The gratings may be amplitude type, phase type, or amplitude and phase type. Moire fringe multiplication under coherent illumination for both homogeneous and inhomogeneous deformation-field is considered. The resulting formulas have universal significance and agree fairly well with the experimental results obtained by D. Post. |
