法布里-珀罗型光纤应变干涉仪

Fabry-Perot optical fiber strain interference apparatus

光纤传感技术是现代通信的产物,是随着光纤及通信技术的发展而逐步发展起来的一门崭新技术。光在传输过程中,光纤易受到外界环境的影响,如温度、压力等,从而导致传输光的强度、相位、频率、偏振态等光波量发生变化。通过监测这些量的变化可以获得相应的物理量。详细介绍了一种常用的干涉型光纤传感器——法布里-珀罗(F-P)光纤应变干涉仪。

Optical fiber sensing technology is a product of modern communications. The development of the new technology is closely related with optical fiber and communication technology development. In the course of optical transmission, the optical fiber is easy to be influenced by the external environment such as temperature, pressure, etc. , leading to the change of light intensity, phase, frequency, and light polarization state, and so on. Through the monitoring of these changes, we can get corresponding physical data. This paper introduced a common interference optical fiber sensing instruments Fabry-Perot optical fiber strain interference apparatus.
