| Abstract: | 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. |
