    Abstract: 本論文提出了一種非接觸光學方法來檢測人體脈搏,主要在於精確確定脈搏在人體的表面,監測其極微小位移量的變化,並可有效儲存脈搏數據,有利於回診時的狀態比對,不僅中醫師了解現況,也可讓病患本身看的到自己病情狀態。
    該方法在於設計一套監測系統,其使用線型感測器 ( Linear CMOS Image sensor ) 搭配非接觸式的光學三角量測 ( Triangulation ) 技術。本研究系統改善了使用傳統陣列式 ( COMS-Array ) 感光元件而構成的光學三角量測系統的量測速度與精度,讓使用者可藉此非接觸式光學量測系統去看見脈搏的寸、關、尺位置處上的頻率變化與差異。
    實驗結果證明了該方法可使脈搏上的變化得以量化及統一標準,將不再有個人的誤差存在其中。該研究成果,將可透過線型影像感測器提供一種脈搏的量測方式,且可解析到 2.5μm的位移變化與每秒高達 200次以上的取樣速度。並將變化的頻率做為長期追蹤與觀察。獲得的數據可以進一步深入探討各脈搏與人體細微的相關性,將頻率、能量與中醫串聯而成,本研究系統能用於中醫及相關醫療上初步的診斷,進而有效及提升看診的便利性。
    根據實驗結果發現:
    A. 橈動脈的寸脈、關脈與尺脈皆位於血管上的位置,跳動訊號顯著。然而,關脈在 1.2Hz 處有易見的振幅,為基頻 0.05Hz 與 0.24Hz 的諧波,推算心跳次數為72下/每分鐘,達一般人的心跳60-100下/每分鐘之標準。
    B. 證明不同脈搏有不同頻率,三個脈搏處皆各自擁有自己的主要組成頻率。關脈位置的主要組成頻率為最多。寸脈主要組成頻率為0.07Hz,關脈為 0.05Hz、0.18Hz、0.24Hz與0.56Hz 四個,尺脈則為 0.04Hz。
    C. 「寸脈」、「關脈」與「尺脈」的峰值在 0.15Hz、0.21Hz與0.41Hz 兩兩交疊集中與靠近,說明了三部脈搏點在同一動脈上。
    ;This paper proposes a non-contact optical method to detect the pulse of the human body, mainly to accurately determine the pulse on the surface of the human body, monitor the change of its extremely small displacement, and effectively store the pulse data, which is conducive to the state comparison during the return visit, not only The Chinese doctor understands the current situation and can also let the patient himself see his condition.
    The method consists in designing a monitoring system that uses a linear CMOS Image sensor with a non-contact optical triangulation technique. The research system improves the measurement speed and accuracy of an optical triangulation system using a conventional array (COMS-Array) photosensitive element, allowing the user to use the non-contact optical measurement system to see the pulse, Frequency changes and differences at the position of the off and the ruler.
    The experimental results prove that the method can quantify the pulse changes and unify the standard, and there will be no personal error. The research results will provide a pulse measurement method through the line image sensor, and can resolve to a displacement change of 2.5 μm and a sampling speed of up to 200 times per second. The frequency of change is used as long-term tracking and observation. The obtained data can further explore the subtle correlation between each pulse and the human body, and combine frequency and energy with Chinese medicine. This research system can be used for preliminary diagnosis of Chinese medicine and related medical treatment, thereby effectively improving the convenience of visiting.
    According to the experimental results, it is found:
    A. The infarct, vein and vein of the radial artery are located on the blood vessel, and the beating signal is significant. However, the Guanmai has an easy-to-see amplitude at 1.2 Hz, which is a harmonic of 0.05 Hz and 0.24 Hz at the fundamental frequency. The estimated number of heartbeats is 72/min, which is the standard of 60-100 beats per minute for the average person.
    B. Prove that different pulses have different frequencies, and each of the three pulses has its own main composition frequency. The main component frequency of the pulse position is the most. The main component frequency of the inch pulse is 0.07 Hz, the pulse is 0.05 Hz, 0.18 Hz, 0.24 Hz and 0.56 Hz, and the ruler is 0.04 Hz.
    C. The peaks of "inch vein", "guan pulse" and "foot vein" are concentrated and close at 0.15 Hz, 0.21 Hz and 0.41 Hz, indicating that the three pulse points are on the same artery.
