  • Abstract  In Chinese medicine, the doctor feels the pulse to judge patients' condition. They learn the technique by teacher’s describing and book and himself experience. They didn’t have the data to describe patients' condition. It will be studied easily if the pulse be quantification.
     We use no contact optical triangular measurement. The setup use SRD (Super Radiance Diode) for light source. And the light received by CMOS image sensor. Then we use MATLAB and Origin to analyze data. We finally get the amplitude and spectrum. The light was laser previously. Here, we use SRD to replace laser. Then the image on the skin will be small (251 112pixels). The light is so small that scattering effect will be weak. And we remove hand’s shake by a technique which is projecting another light to radius. So we can take the second light be a displacement which is hand’s shake. Take the original light data subtract from the second light data. So we can neglect hand’s shake. The result will approach true pulse.
     After adjusting, resolution of experiment setup is 7μm. And we test three kind of stimulus subjects: smoking, spice and eating. We take statistics’ method P value to test the three conditions. Then the amplitude which is the position Guan of left hand is getting strong after smoking. The amplitude which is the position Cun of right hand is getting strong after eating peppery food. The amplitude and frequency are getting strong on Guan of right hand after eating. And the frequency is getting strong after eating.
     In above three subject, it provide for sense of data that we can know how much amplitude is. But the number maybe can’t represent what Chinese medicine says. It need more sample to compile data to compare with Chinese medicine.
