摘　　要：光纤干涉仪是一种具有灵敏度高、抗电磁干扰的相位检测仪器,为了设计性能更好的光纤干涉仪,提出一种基于光电检测电路的光纤干涉仪。首先对光纤干涉仪的工作原理进行分析,并阐述了光电检测系统和转换电路的工作过程,然后设计了一种基于光电检测电路的光纤干涉仪,最后采用仿真软件Matlab 2012进行模拟实验,结果表明,光纤干涉仪的光电流与输出电压间变化曲线与理论值拟合好,其具有广泛的应用前景。Fiber optic interferometer is a phase detection instrument with high sensitivity and anti electromagnetic interference. An optical fiber interferometer based on the photoelectric detection circuit is proposed in this paper. It has better design perforinance. First of all,the work principle of fiber optic interferometer and the photoelectric detection circuit is analyzed,and the design process of the photoelectric conversion circuit and the preamplifier circuit are described. Then a fiber optic interferometer is designed. Lastly,the simulation software Matlab 2012 is used to simulate the experiment. The results show that the optical fiber interferometer light current,the output voltage changing curve and the theoretical values are very close,and they have wide application prospect.
