本文介绍了激光全息无损检测的基本原理,并采用加压加载的方式对玻璃钢筒进行激光全息试验,从激光全息照片中的干涉条纹可计算得到玻璃钢给构的机械性能。
In this paper, the basic principles of laser holographic non-destructive testing are introduced, and the laser holographic test is conducted on the fiberglass barrel by means of pressurization and loading. The mechanical properties of the fiberglass feeding structure can be calculated from the interference fringes in the laser hologram.
