研究期間:10108~10207;This research ism going to build up an optical IR pulse diagonestic sensor head, to measure human pulse to the measurement datum. This research is going to product an optical IR pulse diagonestic sensor head:By taking advantage of IR moiré image, we can measure the pulse vibrated 3D wave form and get the max point shot, then we laser spot on the IR max point. And calculating the light spot center of mass by matlab and triangular formular. We can get the variation of the pulse. At last we use FFT(Fast Fourier Transfer)to get the frequence of the pulse. The structure of this system is simple and accuracy.( the degree accuracy is 10μm). We use these datum to compare with ECG datum simultaneously and get the analytic correlation. This project will get the pulse variation quantitively result.
