Abstract

Blood lead detecting can make certain valuation to human being health and environment problem. Traditional blood lead detecting instrument used only in laboratory analysis with long time and relatively expensive cost disadvantage. Based on small volume and strong anti-interference of fiber sensor, the paper designed fiber system, including fiber sensor and demodulate system, which can be used in blood lead measurement. Using compound environment fixed in fiber sensor, fiber transferred the reflected light with Pb consistency information, then the impatt diode receives modulated light intensity and demodulates to corresponding lead thickness. with designed fiber system, the paper measured some blood samples with 2.67% precision and 0.231 variance. The designed fiber system is very considerable and usable.
