Abstract：Aiming at the power line interference and baseline wander problem existed in the application of photoelectric sensor to detect the pulse signal of human body, propose to use the algorithm of adaptive coherent template and wavelet transform, filter the power line interference and baseline wander respectively, avoid the problems of poor anti-interference ability,instability,waveform distortion and so on when simple use of hardware filter circuit, effectively retained the pulse wave signal in physiological and pathological information.Through the extraction of weak pulse signal, recording and analysing the value of SER, quickly and accurately obtained peo-ple′s pulse wave frequency, amplitude, objectively derived the human health status.
