Abstract
A velocimeter using speckle phenomena in self-mixing laser diodes (SM-LDs) is used to evaluate the blood flow noninvasively, The mean frequency of the speckle signal obtained from the self-mixing laser diode reflects the acti vity of the blood now in a certain probing area. The experimental results s how that this new type of speckle velocimeter can be useful for the relativ e evaluation of blood flow in human tissues.
