Abstract

This paper describes the use of a speckle correlation method for measurement of object velocity. A basic concept of the measurement method is presented briefly. Relations valid for propagation of speckle fields in the image field between the speckle motion and the object displacement are mentioned. An experimental arrangement for the measurement of in plane object velocity including its possible measurement resolution and accuracy is analyzed. Obtained experimental results are shown, too.
