微振动的测量在科学技术和工业应用中都有着重要的意义.比如在材料性质的研究中,在高速转动系统的测量和研究中,以及在实现重力波接收的努力中,微振动的测量都是很重要的一个方面。 激光和无线电技术的结合,实现了光频范围的外差测量,利用它的灵敏度高的特点,我们做了一个测量
The measurement of micro-vibration is of great significance in both scientific and industrial applications, such as in the study of material properties, in the measurement and research of high-speed rotating systems, and in the efforts to achieve the reception of gravitational waves Is a very important aspect. The combination of laser and radio technology to achieve the heterodyne measurement of light frequency range, the use of its high sensitivity characteristics, we made a measurement
