| 摘 要： | 用多光束入射贴有全息胶片的振动物体,对其进行时间平均曝光,在一张底片上可以记录到三维振动振幅信息的多组云纹。利用光栅衍射方向的差异,容易在彼此分开的方向上观察不同的云纹,据此可定量分析振幅的各个分量,无需进行复杂的光学滤波处理。

| Abstract: | A method is developed for measuring 3-D vibration with sticking film moire inter-ferometry. 3-D vibration informations of the specimen have been obtain on the same film bytime-averaged exposure method. The moire patterns, which is used to analyzed 3-D vibration,can be easily observed in different direction. No optical filtering needs. In this paper, rigoroustheoretical analysis is given and experimental demonstration is conducted successfully. |
