In this study we present a new Laser Doppler Velocimeter (LDV) with an optical fiber to measure the velocity of blood flow accurately. After the validity of the present method was evaluated by the fundamental experiments, the blood flow profiles in canine femoral arteries were measured in anesthetized mongrel dogs. It was shown that our LDV is a valid and useful velocimeter to measure the phasic blood flow velocity in the artery.
