Research on Integrative Transceiver Module Applied in FOG

基于干涉型光纤陀螺的小型化和工程化设计要求,研究了一种新颖的收发一体模块,从对SLD光源进行建模入手,设计了小型化的光学系统。并用Zemax软件进行了仿真。这种收发模块采用全保偏技术,体积小,可靠性高,可以有效地抑制光源与耦合器的串音干扰。与应用较为广泛的混偏技术相比,可以避免温度变化、振动等原因对光纤陀螺系统精度的影响,从而提高光纤陀螺的整体性能。

For the purpose of minimizing and industrializing interferometer fiber optic gyroscope （IFOG）, a novel integrative transceiver module is studied in this paper. According to the model of SLD, a compact optical system is designed. Then, the sinulation is carried out by using the software of Zemax. This transceiver module adopts the full polarization-preserving technique. It has advantages of small formation and high reliability. Comparing to the depolarization technique, the effect of temperature change and vibration will be avoided, hence, the whole performance of IFOG; can be promoted.
