摘　　要：以细纤芯及包层光纤为传感头,利用简单的熔接方法,制作了一种多用途MZI全光纤传感器。利用一段多模光纤作为模式耦合器激发细光纤包层模式,可实现对外界液面、折射率、温度和轴向应力的测量,同时利用液面灵敏度大小实现对折射率高灵敏度测量的方法,有助于推动光纤传感器在传感领域的广泛应用。The fine-core and clad fiber is used as the sensor head by simple fusion method to produce a versa- tile all-fiber MZI sensor. And a model of some multi-mode fiber is used as mode coupler to excite cladding mode of TF, to achieve measurement of the external surface, the refractive index, temperature, and axial stresses. Then the method to achieve high sensitivity measurements of the refractive index is used by the size of level sensitivity, which is helped to promote the sensing fiber widely used in the sensors field.
