摘　　要：基于弯曲光纤研发了脉搏测量系统。首先根据光纤的弯曲损耗理论设计了光纤传感头,然后对采集到的数据进行处理,提取和分析特征点。通过测量人体运动前后、不同年龄、不同性别的脉搏信号,发现人体运动后潮波消失,频率和幅值明显增大,中年人的潮波、重搏波峰、重搏波谷不如青年人的明显,女性的脉搏压力差较男性明显偏小。实验结果表明,基于弯曲光纤的脉搏测量系统可以再现脉搏信号的细节参数,能够准确测量到主波、潮波、重搏波峰、重搏波谷等特征点,该研究对促进数字脉诊技术的发展有重要意义。Herein,a pulse measurement system based on bent optical fibers was investigated.First,an optical fiber sensor head was designed according to the bending loss theory of the optical fiber.Then,the collected data were processed,and the feature points were extracted and analyzed.When the pulse signals for different people with different ages and genders were measured before and after exercise,the tidal wave disappeared after the exercise,and the frequency and amplitude of pulse obviously increased.The tidal wave,dicrotic wave peak,and dicrotic wave trough of middle-aged people were not as pronounced as those of young people.Women showed a significantly smaller pulse pressure difference than men.Experimental results showed that the pulse measurement system based on the bent optical fiber could reproduce the detailed parameters of the pulse signal and accurately measure the main wave,tidal wave,dicrotic wave peak,dicrotic wave trough,and other characteristic points.These properties are significant for developing digital pulse diagnosis technology.
