Moire auto-measurement in the muscle pulsing

The paper focuses on the moire technique as a tool of biomedical measurement. The real advantage of moire measurement in muscle pulsing lies in solving no contact requirement problems for which the measured system need whole field monitoring and quickly response. With moire optical measurement system and a video camera we obtained the detail analysis of the behavior of muscle pulsing. Post-processing procedures were performed by an image processing system. The moire system was compared with a fiber optical sensor, our fiber sensing head is multiple fiber bounding with novel devices to prevent the confusing on front slop and back slop in the relation of displacement and signal intensity. The fiber optical sensor give the reference displacement and velocity value of the major point of the muscle. In this study we also discussed the possible applications of the moire auto-measurement system in the muscle pulsing.
