将全息胶片粘贴到测试表面,利用全息干涉两次曝光法,获得高灵敏度二维云纹;曲于实现了制栅和测试过程的合一,胶片与试件分离后处理,本方法具有简易、省时、灵活,试验费用低,适用面广,可用于现场在位测试等优点。
The holographic film is pasted to the test surface, and the holographic interference double exposure method is used to obtain the high-sensitivity two-dimensional moiré. The method achieves the combination of the fabrication grid and the testing process, the separation of the film from the test piece, the method has the advantages of simpleness, Save time, flexibility, low test costs, wide range of applications, can be used for on-site testing and other advantages.
