Abstract
The operating principle of an ultrasonic speckle velocimetry technique of flow-velocity measurement is described. This method allows the quick determination of the velocity of an object on the basis of a simple statistical process involving counting the local intensity fluctuations of the echo signal from the object. The results of a basic experiment to verify the effectiveness of the proposed method are presented. It is also shown that there is a linear relationship between the flow speed and the number of speckle intensity fluctuations.
