摘　　要：鉴于双光路通道差动测量方法能够有效去除共模干扰,本文将新型电路元件—忆阻器与传统的光纤式结冰传感器相结合,提出了纳米级尺寸具有放大效应的忆阻桥网络结构,分析了忆阻桥的放大效应原理,实现了光电二极管光电流信号的放大,以桥臂忆阻阻值和感知忆阻两端电压作为传感输出,对冰层厚度进行探测。仿真实验结果表明:该双测量通道忆阻桥网络结构能够同时有效消除光路扰动和扩大结冰厚度的测量范围。Considering the effectiveness of double optical path method for solving common-mode interference problems,a memristor-bridge structure is proposed,which has signification amplification effect with nanometergrade area. Application principle of photocurrent in the photodiode is analyzed. The memristor-bridge detects the ice thickness by sensing voltage across the perception memristor. Simulation results show that the structure is capable to eliminate optical path disturbance and enlarge ice thickness measurement range.
