In order to establish the quantitative method for measuring three-dimensional displacements by holographic interferometry, the authors have already discussed some problems and presented several practical devices. On the basis of these considerations, the usefulness of this measuring method was shown by a practical example: measurement of deformation in a cylindrical shell under concentrated loading. The displacement components could be measured with high accuracy (order of 0.1 microm) when the optical system was arranged and the fringe order number was read within allowable error given beforehand, respectively. The decision of fringe order number was made easily by applying elastic elongation of a rubber strip as an index and by reconstructing the holographic real image on the original object.
为了建立用全息干涉术测量三维位移的定量方法，作者已经讨论了一些问题并提出了几种实用装置。基于这些考虑，通过一个实际例子展示了这种测量方法的实用性：测量集中载荷作用下圆柱壳的变形。当分别布置光学系统并在预先给定的允许误差范围内读取条纹级数时，位移分量能够以高精度（0.1微米量级）进行测量。通过将橡胶条的弹性伸长作为指标并在原始物体上重建全息实像，可以轻松确定条纹级数。
