测量单模振动的时间平均曝光法

Detection the Single Mode Vibration by Using the Time-Averaged Technique

采用ＭａｃｈＺｅｈｎｄｅｒ干涉仪测量简谐振动．引入圆柱形透明介质对物光束调制，产生一组带有振动信息的散斑干涉条纹，由此确定振动参数，同时提高测量灵敏度．

The article adopts Mach Zehnder interferometers to measure sinusoidal vibration. By using cylinder transparent medium to modulate objective lights, we can obtain a series of speckle interference fringes with vibrating information, with which we can determine the vibrating parameters and improve the sensitivity of detection.
