Abstract EN
Pulse diagnosis is one of the four diagnostic methods of traditional Chinese medicine.
However it suffers from the lack of objective and efficient detection method.
We propose a noncontact optical method to detect human wrist pulse, aiming at the precise determination of the temporal and spatial distributions of pulse.
The method uses the spatial-carrier digital speckle pattern interferometry (DSPI) to measure the micro/nanoscale skin displacement dynamically.
Significant improvements in DSPI measurement have been made to allow the DSPI to detect the comprehensive information of the arterial pulsation at locations of Cun, Guan, and Chi.
The experimental results prove that the spatiotemporal distributions of pulse can be obtained by the proposed method.
The obtained data can be further used to describe most of the pulse parameters such as rate, rhythm, depth, length, width, and contour.
