A Single Doppler Shift of Laser Doppler for Measured Average Velocity

Abstract

According test the results from samples of clinically normal for ages(20-59) and diabetes mellitusfor measure of blood concentration and resolved velocity by a single shift of laser Doppler flowmetry based on illuminated laser beam on the foot has been reported in this paper of patient safety and noninvasively. The main research to arrive a simple method noninvasive and get more information about the resolved velocity to diagnose the nature of disorder blood flow for different person by using low power laser source, coherent light without thermal effect upon living tissue.
