摘　　要：通过理论分析建立了扭转高双折射光纤的数学模型,提出一种利用扭转高双折射光纤实现光纤光栅反射波长的解调方法。理论和实验表明,该系统具有10nm的准线性解调制范围,线性度好,易于实现。The mathematical model of twisted high birefringence fiber was established through theoretical analysis. A novel FBG wavelength demodulation method was put forward by using twisted high birefringence fiber. Theory and experiment show that the system has a guasi-linear demodulate scope 10 nm for good linear, and can be easily realized.
