Abstract

In this paper, A heart-throb acquisition technique based on laser self-mixing is proposed. In view of the characteristics of extremely weak vibration of human heart-throb, a multiple reflection method is proposed. The objective of the external cavity is to improve the measurement accuracy by / 5. Fringe counting algorithm, A periodic heart-throb is successfully reconstructed. The measurement results show that the root mean square error (RMSE) the reconstructed heart-throb was 0.813 m at 9kHz sampling rate. In addition, correlation coefficients. And heartbeat were analyzed by this method and conventional photoelectric volume meter (PPG) measurements.
