摘 要: 激光回馈现象得到了广泛的研究和关注,而多普勒测速是激光回馈研究中的一个重要分支。介绍了激光回馈多普勒测速技术的基本原理,以及3种不同类型的基于激光回馈原理的多普勒测速技术,总结了其工作原理以及优缺点,并对激光回馈多普勒测速技术的发展方向进行了探讨。 Laser-feedback phenomena have been extensively investigated and concerned, and Doppler velocimetry is one of the important branches of laser-feedback research fields. The basic principle of laser-feedback Doppler velocimetry was introduced. Then the structures, principle, advantages and disadvantages of three types of laser Doppler velocimetry based on feedback effect were reviewed and discussed in detail. Finally, the development of velocity measurement based on laser feedback effect was also discussed.
