Abstract
A new noninvasive technique for monitoring capillary blood flow has been developed. Based on the phenomenon of time-varying laser speckle, it is a digital version of single-exposure speckle photography. It provides a velocity map of the area of interest in real time without the need for scanning. The results of some initial experiments on volunteers are presented.
