【摘要】：基于双光束干涉理论和维纳辛钦定理,推导出宽谱光源干涉特性的表达式并进行了分析。提出了基于迈克尔逊干涉仪光路测量光源自相干函数的方法。在光学设计软件Zemax的混合序列模式下建立了宽谱光源自相干函数测试系统的光路模型,通过多重结构编辑器对参考光路和测量光路进行了仿真。单独对准直系统进行了仿真,通过优化使系统的光线准直效果达到最佳。并根据仿真建立的理论模型,从光纤纤芯大小和对准误差这两个角度分析了它们对光线准直系统准直度和整个系统耦合效率的影响,得到对应的变化规律,最后通过Origin软件绘制出了相应的变化曲线,为搭建宽谱光源自相干函数测试系统提供了基础。
[Abstract]:Based on the theory of double beam interference and the Wiener Sinchin theorem, the expression of interference characteristics of wide spectrum light source is derived and analyzed. A method of measuring the self coherence function of light source based on Michelson interferometer is presented. In the mixed sequence mode of the optical design software Zemax, the optical path model of the wide spectrum light source self-coherence function test system is established, and the reference and measurement optical paths are simulated by a multi-structure editor. The alignment system is simulated and optimized to achieve the optimal light collimation effect. According to the theoretical model established by simulation, the influence of the optical fiber core size and alignment error on the collimation degree and the coupling efficiency of the whole system is analyzed, and the corresponding variation law is obtained. At last, the corresponding curve is drawn by Origin software, which provides the basis for setting up a wide spectrum light source self-coherence function test system.
