| 摘 要： | 当透明介质中有畸变时，介质均匀部分与畸变部分的透射光经过透镜变换后，在透镜后存在交叠。将ＬｉＮｂＯ３Ｆｅ晶体置于两光交叠处，利用ＬｉＮｂＯ３Ｆｅ晶体光放大作用，可以将透射图案的对比度大大提高，从而实现畸变的检测。此方法十分简便，灵敏度较高

| Abstract: | When there are distortions in transparent media, a light through uniform parts and distortions of the media will overlap each other after the transformation of a lens. By the amplification of LiNbO 3:Fe crystal placed at the place where the two kinds of lights coincide, the contrast of the transmitted pattern will increase greatly and then we can detect the distortions in the transparent media. This method is quite simple and has high sensitivity. |
