Abstract This paper proposes a new idea for arterial pulse detector using precisioninstrument with fiber optic sensor and describes theory,experiment set up and the resultingof the apparature, The fiber optie sensor consists of detecting part that is composed fromspecial structure and fiber sensing part which has elastic reflector and optical fiber. The de-tecting part can detect changing arterial pulses and transmits it to the reflector,which will beinclined with the intensity of the arterial pulses, In sensing part, the reflected beam will beproportional the displacement changed by inclindreflector and transformed into electricalsignal. After signal processing, the picture of arterial pulses display in the oscilloscope, Thepractical resulting proves that it will provede a clinically usefuI tool in field of chines tradi-tional medicine and has a simple structure and high precision.
