For measurement of local blood velocity, a less-invasive miniaturized fiber-optic LDV (laser Doppler velocimetry) sensor was developed as a monitoring device for clinical use. By the method of a chemical etching, a convex lens-like surface was formed on the fiber tip. Laser emitted from the tip was focused and formed measuring volume, which enabled us to measure the velocity of steady blood flow in previous study. In order to measure local velocity of pulsatile blood flow, the optical system and the best curvature radius of the sensor tip were newly designed. By the present fiber-optic LDV sensor, local velocity and its profile in the flow duct were successfully measured in pulsatile flow of a dense suspension with the same optical property as blood, which proved the capability of the sensor as a diagnostic device.
