Since the surface plasmon resonance technology was firstly used in sensor field, thedevelopment of this technology is amazing in these thirty years. It has so many advantagessuch as no label, high sensitivity, real-time analysis and small amount of sample. This makesit possible that SPR technology is widely used in physical, chemistry, biological and otherrelated fields. SPR sensing theory has already become a key technology, especially in lifescience, drug residue detection, environmental monitoring.The SPR detection technology is increasingly sophisticated and the extensive of thecommercial market. That indicates the huge potential for development of this technology.Nowadays people pay more attentions on their health, so SPR sensor used in drug residuedetection has greater prospects for development. However, till now of all the researches onSPR, there is seldom a research that relates to Chinese traditional medicine detection. As thebirth place of the Chinese traditional medicine, there is not any kind of detections with bothlow cost and high efficiency. China distributes a less part of Chinese traditional medicinemarket than other countries in Asia. Based on these situations, bring new sensor technologiesto Chinese traditional medicine industry is imminent.The emphasis of this paper is to detect the Chinese traditional medicine using the SPRsensing technology. The detection system is a SPR sensing system based on wavelengthmodulation. This system has a better stability and anti-disturb, and will have a better accuracy.By working on theoretical derivation of SPR sensor technology, we deeply analysis thefactors that will affect the sensor system, then running and improving the simulation programto reduce the inconsistent between theoretical and experiment. Finally we use this system todetect seven kinds of Chinese traditional medicine, the result shows that SPR sensortechnology can be used in detection of Chinese traditional medicine, with easy operations andwithout pre-processing. This indicates the huge potential for development in this field.
