摘　　要：针对低成本光纤陀螺的电路检测方案开展研究,提出一种模拟解调、方波调制和阶梯波反馈的闭环方案。在对光纤陀螺信号检测理论分析的基础上,设计了模拟解调电路、数字逻辑电路等,并进行了样机测试。测试结果表明,指标达到了低精度光纤陀螺的性能要求,说明该方案可行。In the study of circuit detection scheme for the low-cost Fiber Optic Gyroscope（FOG）,a closed-loop scheme for analog demodulation,square wave modulation and step wave feedback was put forward.Based on the analysis to signal detection theory of FOG,the analog demodulation circuit and digital logic circuit etc were designed,and prototype test was carried out.The testing results indicated that the index has reached the performance requirement of the low-precision FOG,and this scheme is feasible.
