| dc.description.abstract | The main purpose of this paper is to present an optical measurement system to monitor and measure the height and micro-movement of the surface. This measurement system includes an infrared laser, an infrared image sensor, a moiré reference grating and a personal computer.
Using the shadow moiré combing with the MATLAB program designed by ourselves, the out-of plane displacement of the surface can be calculated by the change of the moiré fringe, and monitored with the time rapidly and automatically. Second, we enhance the ability of system to measure the contour map at the same surface. Third, taking advantage of the regional measurement of the moiré, we enhance the analysis from one point to a line and an area. Thus, we indeed set up a 3D surface monitor system which can catch the situation of the surface entirely and more efficiently.
This moiré monitoring system used in TCM pulse diagnosis. According to the steps of pulse diagnosis of Traditional Chinese Medicine(TCM), we can catch pulse waveform, which caused from the vibration of our skin at the three points on the wrist called Chun , Guan, and Chy point.
Another focus of this paper is that using infrared light and photographic equipment supersedes the visible light source and photographic equipment, the use of infrared penetration, so that the system can only be measured prior to the skin surface modified into the shortcomings of the measured pulse beneath the skin of the vibration, making closer to the true measurements of the pulse. | en_US |
