A new fiber optic sensor for detecting in situ the concentration of pharmaceutica in blood

摘要

This paper introduces a new fiber optic sensor which cna detect in situ the concentration of pharmaceutical in blood.An opticla fiber probe insert in the blood vessel,ultraviolet light is coupled into one branch of Y-type opticla fiber beam and propagated to hte probe to induce the pharmaceutical in blood to emit fluorescence,which is collected yb the same probe and propagated to another brance of Y-type optical fiber beam and received by a spectrometer.
