    Abstract: 本研究擬製造一光學感測整合系統:?用疊紋法定位脈搏位置或寸關尺脈的位置,再用三角測?法?測人體脈搏;首先我們先運用MOIRE(疊紋),可較準確定位出脈搏位置,再?用紅外線?射打在待測點上,並以MATLAB軟體計算影像感測器紀?的光點質心的變化,由系統中三角關係可求出脈搏振幅變化的大小,最後運用FFT(Fast Fourier Transfer 快速傅??轉換)求出脈搏波的頻?,此一系統結構簡單且?確(?確?可達10um)。中醫方面有二十八種脈象,但是至今仍很難?化,而本計畫的特點就是提供中醫評估工具?化。目前有進行壓?感測器的研究,尚未有用非接觸式的;本計畫之紅外線?射三角測?法屬非接觸式地??測人?脈博波,且本研究擬與中醫界配合,以自己開發的光學?測系統?建?健康受測者資?庫,將中醫的脈診透過光電系統而?化,製成方?家用診斷末端感測系統之診斷知?庫,做家護健診之用,以期能對中醫的科學化有所貢獻。目的: 1.推動中醫把脈科學化、量測技術引進。 2.協助建立中醫診斷規範,評估工具之標準化。 3.運用新研發產品為產業帶來居家性、便宜、可量產之新產品。本研究可以培植光學、電子及醫學、生物之研究人才,做為企業界未?的高等研究人?,增進產品附加價值,此項產品運用在其他產品,如血?、血含氧?之偵測,應用的潛?很大。 There are a lot of measurement methods or equipments for measuring the pulse of human being, including palpation, stethoscope, sphygmomanometer, electrocardiogram (ECG), oximeter, pressure transducer, optical interferometer, Doppler-based instrumentation, and this optical triangulation pulse measurement system we proposed here. Arterial pulsation waveform has been considered as fundamental indicators in the diagnosis of cardiovascular disease and guide therapeutic decision in complex clinical situations. Abnormality of shapes and frequencies of palpation are symbols of certain cardiovascular disorders, thus how to pick up arterial pulse waveforms without distortion has become an important issue in biomedical signal processing. On the other hand, pulse diagnosis is the one of four kind diagnosis methods to determine the physiological condition of patients in Traditional Chinese Medicine (TCM). In clinic, most popular methods applied to measure pulse behavior include stethoscope, sphygmomanometer, and Doppler-based instrumentation. In TCM, most studies of pulse diagnosis machine use other devices to record pulse changes. A set of three pressure transducers to sense three location pulses has been proposed. Lu and Wang analyzed the harmonics from the frequency spectrum of pulse waves and related some illness condition to certain harmonics. The devices used in these studies could either interfere in the measurement because contacting or cost more as having additional sensors for multiple points probing. No touch pulse measurement with optical interferometer was proposed by Hong et.al, it can estimate skin vibration velocity. Echo-metric techniques which would make use of time-of-flight measurements of an energy pulse reflected from points on the object are not practical at short rangers due to very short time intervals that have to be measured. An optical non-contacting technology, which based on optical triangulation, is proposed in this study. Optical triangulation is well known in thickness and contour measurement, and applied to many industrial fields. This study will conduct the design of the pulse measurement system and verify the pulse measurement accuracy, then using this pulse measurement system to build a complete data base by measuring the patients. Moire’ will be used to locate the top of the pulse, then the vibration and frequency of the pulse will be record with this IR laser pulse measurement. 研究期間:9508 ~ 9512
