本文以张量分析作为数学手段,将研究物体形变的运动学与全息像的形成相结合,利用光程差及光程差的一阶、二阶微商导出漫射物表面及内部应变与转动测量关系式。采用单张全息图的ZFC(零级条纹和条纹计数相结合)条纹观察法,测量了玻璃钢压力容器的位移、表面应变及内部应变,其结果与应变仪的结果一致。 In this paper, tensor analysis is used as a mathematical method to combine the kinematics of object deformation with the formation of holographic image. Using the first-order and second-order derivative of optical path difference and optical path difference, the surface and internal strain and rotation of diffuser Measuring the relationship. Using ZFC (zero-level fringe and stripe counting) fringe observation with a single hologram, the displacement, surface strain and internal strain of the FRP pressure vessel were measured. The results are consistent with those of the strain gauge.
