| 摘 要： | 将全息胶片粘贴到测试表面,用加载前后两次曝光法得到全息云纹,再将胶片与试件分离进行后处理,这种可分离处理的贴片云纹干涉法,使高灵敏度与技术的简易性溶为一体,试验周期缩短,成本降低,並可直接在工程材料和构件上贴片、测试,提出並证明了实现透射式云纹干涉法实时条纹观测的条件;还阐述和证明了控制衍射效应影响的斜照射守则。遵循此守则,可实现高频透射栅的复制及简化透射法光路。

| Abstract: | Stick the holographic film on the surface to be measured. Expose the film before and after loading, and two gratings are recorded. Then remove the film. Develop, fix, and illuminate the film and then obtain a reconstructed clearly visible moire' pattern. This technique is simple and has a high sensitivity. With this technique the experimental cycle can be shortened, and expenses can be reduced.
This paper presents the principle and condition of observing the real time fringes in transmissible moire' interferometry, and explains the regulation of oblique illumination and the applications as well. |
