Paper Abstract

This paper presents a non-invasive, non-contact measurement of pulse waveforms by applying optical triangulation technology on skin surface vibration. The arterial pulsation information can be obtained with this measurement system. An algorithm to evaluate the pulsing activities from center of laser spot intensity on a certain wrist point has been conducted by fast Fourier Transform (FFT). The amplitude and frequency of skin vibration can be known by this measurement system. The advantages of this optical triangulation method are non-contact, low cost, remote sensing, and it can be combined with image processing system.
