超音波都卜勒信號之試管量測與分析

Abstract

The object of this experment, is to discover the wave propagationof the ultrasonic wave in the blood. On the other hand, we were mainly devoted to the source of the scattering machanics in the blood. In ourexperiment, we use the chalk to substitute for the blood. And we were truely capture the ultrasonic Doppler shift frequency, because the moving chalk. We were change the velocity to gain the difference of the ultrasonicDoppler shift frequency.
