摘要
在光纤陀螺中,耦合器的性能变化对陀螺的稳定性有很大的影响,对光纤耦合器性能的分析研究对光纤陀螺的进一步发展具有重大意义。本文对耦合器分光比、损耗及偏振串音特性进行了理论分析与实验研究。基于LabVIEW和Matlab工具的发展和应用,结合两者的优点和实验室的设计需求,设计出了一个便捷、直观、实用性强的耦合器性能分析平台,通过该平台选取出了性能比较好的实验室自制耦合器,便于实际光纤传感系统中不同性能要求的耦合器的选取。
In FOG,the changes in the performance of couplers has a great impact on the stability of the gyroscope.The analysis of the performance of optical fiber couplers is of great significance to the further development of fiber optic gyroscope.The characteristics such as splitting ratio,loss and polarization crosstalk of coupler were analysized theoretically and researched in the experiment in the article.Based on the development and application of LabVIEW and Matlab tools in the automation field,combined with their advantages and laboratory design needs,a convenient,intuitive,strong practical Coupler Performance Analysis platform was designed.By the platform,good-performance coupler was selected from many laboratory-made couplers in order to select couplers with different performance requirements in the practical optical fiber sensing system.
