The pulse is one of the important human physiological parameters, and the non-contact acquisition of pulse waves holds significant clinical application value. This paper proposes a method for amplifying the original vibration signal of the radial artery skin surface using Moire fringe technology under LED light, enabling the detection of pulse waves by recording the pulsation of the radial artery through continuous frame imaging. In the experiment, a striped thin film was adhered to the surface of the radial artery, and another set of stripes was placed 2～3 cm away from the artery formed Moire fringes under LED illumination. An industrial camera was used to continuously capture a sequence of images showing the periodic movement of the Moire fringes caused by radial artery pulsation. A region of interest was selected to extract the original pulse signal, which was then filtered using bandpass filtering and variational mode decomposition to obtain a pulse wave that preserved the detailed characteristics of the pulse. The results of measuring the pulse wave signals from multiple subjects demonstrate that this method can acquire complete pulse wave signals, retaining various features such as the primary wave, tidal wave, and dicrotic wave. The proposed method offers valuable reference for the non-contact acquisition of human pulse waves.
