Resonant Fiber Optic Gyroscope Using an Air-Core Fiber
Gyroscopes photonic-bandgap fi bers resonant fi ber-optic gyroscope RFOG
2012/8/7
Air-core photonic bandgap fibers (PBFs) have great potential for the resonant fiber-optic gyroscope (RFOG), because they reduce both the Kerr-induced drift and the thermal polarization ins...
