【摘要】 针对采用 3×3 耦合器的开环光纤陀螺,研究了一种采用三个探测器进行信号检测的技术方案,建立了比较精确的信号检测模型,并且对信号检测模型中的参数进行了研究,给出了系数公式以及系数求解的方法,同时还分析了所求系数的精度对陀螺零位和标度因数的影响。更多还原

【Abstract】 A signal demodulation method used three detectors for open loop fiber-optic gyroscope(FOG) adopt 3×3 fibre coupler was studied in this paper. The model of signal processing was set up and parameters of the model were also presented in detail. Effects to FOG of these parameters were analysed particularly.更多还原
