光纤全息无损检测的研究

Nondestruction Testing with Fibre-optic Holographic

光纤记录全息图，是对全息术应用领域的一大扩展。本文研究了光纤对全息图的影响，和在连续激光器（ＣＷｌａｒｅｒ）下使用不同的加载方法，对焊缝和复合材料进行光纤全息无损检测。获取了高质量全息图、研究结果表明：应用光纤全息进行无损检测是可行的。最后指出使用脉冲激光器，光纤全息能够进行动态物体的无损检测。

Many problems can be solved by using optical fibre to record hologram. The influence of optical fibre on hologram are discussed in this paper,and the holographic nondestructive testing of seam weld and compound material are carried out in different initialcondition and using different loads. The results show that the fibre-optic holographyrecorded by CW laser and fibre-optic holographic nondestructive testing are applicable.Bassed on theory and experiment,the ways and methods to obtain a satisfied hologramare suggested and can be used for moving object.
