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。
The holographic film is pasted to the test surface, the holographic moire is obtained by the double exposures before and after loading, and then the film is separated from the test piece for post-processing. The detachable patch moire interferometry method enables high sensitivity and technical Simple and easy to dissolve into one, the test period is shortened, the cost is reduced, and the materials and components can be pasted directly on the engineering, test, put forward and prove the real-time transmission line moire fringe observation conditions; also elaborated and proved that the control Gradient effect of oblique irradiation guidelines. By following this code, high-frequency transmissive grids can be replicated and the transmissive method can be simplified.
