| Abstract: | 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. |
