Abstract: Beginning in the end of 1960's,laser-doppler velocimetry (LDV) requiring high-time or high-space resolution and high accuracy with the help of laser technique.Recently,semiconductor technique,optical fiber and computer technique enable the optical system and signal processing of LDV to occur a fundamental change.This paper introduces these new developments of LDV,analyzes the progress trend in the future and points out the importance in scientific research and modern industrial production.
