摘要
近年来,声光调制技术的应用越来越广泛。由于声光衍射测量是非接触测量,因而具有适应性好、精度高、测量时无需接触被测物体等优点,使其在精密测量方面有着很好的应用前景。文中首先介绍了声光调制的概念及其工作原理,然后介绍了声光调制技术在精密测量方面的应用,包括声光调制在速度测量、激光波长测量、频率测量及折射率测量等方面的应用。
In recent years, acousto-optic modulation technique has been widely used in many fields. Because measurement based on the acousto-optic diffraction is non-contact, it has the advantages of good adaptability, high precision and noncontact, which make it a very attractive tool in the field of precision measurement. In this paper, the concept and principle of acousto-optic modulation are first introduced, and applications of acousto-optic modulation technique in the field of precision measurement are detailed, including its application in the measurement of speed, wavelength, frequency and refraction index, etc.
