| 摘 要： | 本文通过对动态散斑光强自相关函数的分析，利用一阶横模的激光束照射在运动的漫射板上，记录散斑光强起伏的频率（单位时间内跨过光强度均值的平均次数）可以同时测量漫射板移动的速度和方向。

| Abstract: | In this paper,an analysis of autocorrelation function of dynamic speckle intensity is provided.A method has been obtained for simultaneous measurement of the magnitude and the direction of velocity of a diffuse object illuminated by a beam of first order lateral mode with recording the frequency of variance of speckle intensity(i.e.the average number cross the average intensity per unit time) |

| Keywords: | dynamic speckle autocorrelation function of field amplitude autocorrelation function of intensity |
