    Abstract: 本論文主要是建立三種不同架構的非接觸式光學量測系統,並應

    systems used in the biomedical field. The first system uses optical moiré to
    automatically determine the location of moiré pattern, record the cycle of
    pattern change and calculate the height and height change at any spot of a
    test surface. This system can analyze the conditions of pulse which include
    the location (image processing of moiré pattern), rhythm (via frequency),
    shape (via moiré pattern) and strength of pulse (via amplitude).
    The second system uses a condenser microphone to measure the pulse of
    wrist. Signals captured by the microphone is filtered and transmitted to a
    computer for a fast Fourier transform (FFT) to be converted into heart rate.
    This device follows the practice of pulse reading in Chinese medicine and
    applies three different pressures of 50mmHg, 80mmHg and 110mmHg at
    wrist, guan and cubit. The two measurement methods above analyze and
    quantify the pulse reading in Traditional Chinese Medicine.
    The third system uses the concept of laser optical triangulation which
    injects different concentrations of formalin reagent into animal to obtain
    different frequencies of stimuli (empty injection, 12% formalin, 37%
    formalin). The results show positive correlation, so that pain can be
