Intermodal interference stress measurement sensors have become an attractive method

Optical fiber sensor with high sensitivity, good reliability, anti-electromagnetic interference, corrosion resistance, high pressure, good electrical insulation properties and other characteristics, has become a research hotspot in the field of sensors. In recent years, based on polarization maintaining fiber mcb circuit breaker  interference principle of fiber optic sensor has been more attention, intermodal interference stress measurement sensors have become an attractive approach. With traditional arms interferometric fiber optic sensors,  Voltage stabilizer  interference sensors have better anti-interference ability and temperature stability, flexible structure can be used to design a variety of fiber optic sensors have been widely used in current and voltage measurements, the sound of water and water pressure measurement, stress measurement and so on.  circuit breakers  the conventional polarization maintaining fiber, polarization maintaining photonic crystal fiber (Polarization Maintaining Photonic Crystal Fiber, PM-PCF) has good temperature stability and higher sensitivity. In a certain wavelength range, polarization maintaining photonic crystal fiber to polarization-mode transmission line LP11 LP01 mode and even mode, these patterns after transmission in the fiber at the output of interference.
