Abstract

A theoretical model of the thermal phase noise in a square-wave modulated solid core photonic crystal fiber-optic gyroscope has been established, and then verified by measurements. The results demonstrate a good agreement between theory and experiment. The contribution of the thermal phase noise to the random walk coefficient of the gyroscope is derived. A fiber coil with 2.8 km length is used in the experimental solid core photonic crystal fiber-optic gyroscope, showing a random walk coefficient of 9.25 × 10 deg/√h.

摘要

建立了方波调制实心芯光子晶体光纤陀螺仪热相位噪声的理论模型，然后通过测量进行了验证。结果表明理论与实验吻合良好。推导了热相位噪声对陀螺仪随机游走系数的贡献。实验用的实心芯光子晶体光纤陀螺仪中使用了长度为2.8 km的光纤线圈，其随机游走系数为9.25×10 deg/√h。
