碩士 === 國立中央大學 === 光電科學與工程學系 === 106 === In this study, we mainly use a 512pixels linear CMOS image sensor with the triangular measurement method, the use of 660nm Laser spot displacement changes to measure the human pulse and acupuncture points. The sensor developed by the Institute, measuring the center point of 50mm, measuring range ± 20 mm, repeat the accuracy of 2.5 μm. To calculate the displacement of the object to be measured to build a simple non-contact measurement of the gage, instead of the naked eye and non-contact to detect the pulse and acupuncture points of the phenomenon, according to the study Results to calculate the displacement of the pulse and acupoints. The number of detection samples up to 200 times per second, then the Fourier transform from in the time-domain signal to frequency-domain conversion, to accurately and quickly capture data and then analyze the functioning of the body. To achieve low production costs and high-precision non-contact pulse diagnosis and acupuncture points with a test. According to the results of this study, "Taiyuan Point" on the "Lung Meridian of Hand-Taiyin, LU" is also known as "Cun pulse" which is also located at the blood vessel position of the pulse. Therefore, the beating signal is strong. The measurement results are peaked at 1.2Hz and as 0.20Hz fundamental frequency of six times. Because it is also a pulse position can be estimated that the heart rate equivalent to 72 beats per minute. 2.4Hz also significant peak response, calculated as 12 times the 0.20Hz frequency. However, the beat amplitudes of the "Daling Point" and "Neiguan Point" measurements on the "Pericardium Meridian of Hand-Jueyin, PC" were iii both lower than those of "Taiyuan Point" on the "Lung Meridian of Hand-Taiyin, LU", showing that "Pericardium Meridian of Hand-Jueyin" acupuncture beating the energy very low. "Neiguan Point" has a maximum of about 0.44 Hz, while "Daling Point" has a maximum of 0.22 Hz. According to the results of the study, we can see that "Neiguan Point" reflects twice the frequency of "Daling Point", and the vibration frequency of the two meridians in the same meridian is an integer multiple of the fundamental frequency. The experimental results also show that the main frequencies detected in the "Pericardium Meridian of Hand-Jueyin" and the "Lung Meridian of Hand-Taiyin" differ by 0.02 Hz. Microscopic point of view, the "Pericardium Meridian of Hand-Jueyin" measurement results have obvious 0.22Hz harmonics, also contains a lower harmonic component of 0.35Hz. the "Lung Meridian of Hand-Taiyin" measurement results have obvious 0.20Hz harmonics, also contains a lower harmonic component of 0.15Hz. This study shows that each meridian carries a lot of frequency and cannot be expressed in a single wave. However, each organ represented by the meridian has a list of frequency signals corresponding to it. The comparison between the frequency of the "Pericardium Meridian of Hand-Jueyin" and the "Lung Meridian of Hand-Taiyin" also proves that each meridian has its own priority frequency, and the operation mechanism of frequencies will be different.
