Abstract

In order to reduce the influence belonging to angle error of the measurement accuracy and improve the measurement accuracy of a laser Doppler velocimetry. The mechanisms of three types of angular errors are analyzed by taking a dual-beam dual-scatter laser Doppler velocimetry as an example in this paper. And then, the impact on measurement precision is analyzed. Subsequently, the methods and principles of automatic correction are discussed. Finally, an experimental system is constructed. Experimental results demonstrate that the system's accuracy significantly improved with correction which enhances from 2.1% to better than 0.3%.
