【Abstract】 Correlation techniques offer a good possibility for contactless measurement of the velocity of continuous surface.Correlation velocity measurement technique features of high accuracy,high speed and high immunity to noise and interference and so is wildly used in many aspects of industry.This paper focused on the system implementation and experiment design.Through digital simulation and the adjusting of system parameters it can demonstrate students the characteristics of stochastic function and correlation function,the principle of correlation velocity measurement technique and how the system parameters affect the system performance.The developed software is a powerful one whose function includes experiment data saving and searching,off-line data analysis auto-reporting and remote experiment interfacing.更多还原
