The fringe-vector theory of holographic strain analysis was applied experimentally to determine strain and rotation tensors of rotated and deformed objects. One object was supported in a specially designed positioner, and the other was heated internally with a temperature controlled device. The rigid body motions and deformations were determined directly from the fringes that were observed on the surface of the object. This was done by taking photographs of the virtual image of the object from several different directions through the same hologram; the photographs were digitized manually, and the parameters obtained were, in turn, analyzed using a computer. The strains and rotations determined experimentally from holograms compared satisfactorily with the theoretical ones.
全息应变分析的条纹矢量理论被应用于实验，以确定旋转和变形物体的应变和旋转张量。一个物体被支撑在一个特别设计的定位器中，另一个物体则通过温度控制装置进行内部加热。刚体运动和变形直接由在物体表面观察到的条纹确定。这是通过从几个不同方向透过同一全息图拍摄物体的虚像照片来完成的；照片被手动数字化，然后使用计算机对获得的参数进行分析。从全息图实验确定的应变和旋转与理论值比较令人满意。
