生命体征监测对于人的日常生活、生命健康都有极其重要的意义。目前，对生命体征信号的监控可以分为侵入式和非侵入式。侵入式监测仪器基本上都是需要将探测器或者传感器紧贴待测者皮肤或者心脏，才能获得比较准确的信息。然而，侵入式监测仪器难以避免交叉感染、抗电磁干扰等问题，而且，侵入式监测对于待测者的舒适度有较大影响，待测者可能会产生情绪波动以致影响到测量的准确性。
非侵入监测有较大的技术优势，对于待测者不需要贴紧皮肤或者心脏，即可进行实时准确的生命体征监测。目前市场上也有一部分基于电子传感器的生命体征监测产品，但是难以在电磁环境比较大的情况下使用，比如核磁共振。综上所述，以往的生命体征产品都有以下一种或多种不足：

所述第一光纤9和第二光纤6分别为任意类型光纤，所述参考光纤3和所述传感光纤4分别为任意光纤，且波长没有限制。所述激光光源1是连续光或者脉冲光的单波长激光器，包括DFB激光器、VCSEL激光器等，同时激光光源发出的波长不限制，涵盖所有波段，适用性强。

Figure PCTCN2016104283-appb-000002
相位差为
Figure PCTCN2016104283-appb-000003
参考光纤和传感光纤的有效折射率分别为波长neff1和neff2，波长为λ，光电探测器接收到的光强为IPD，不考虑光纤损耗，则
Figure PCTCN2016104283-appb-000004
Figure PCTCN2016104283-appb-000005
人体的体动、呼吸、心跳等微扰会影响光纤的有效折射率和长度，并影响相位差和IPD。因此，根据接收到的光强再根据生命体征提取与分析算法，就可以得到生命体征信号。
综上所述，本发明指出的一种全光非接触式生命体征监测装置，本发明提出的全光非侵入式的基于MZI的生命体征监测装置与方法，可以有效克服以上不足，利用全光纤MZI进行人体的生命体征监测，完全可以达到非侵入式监测，具备抗电磁干扰、无交叉感染、舒适性好和灵敏度高等优点。
