摘要
分析了由三根单模保偏光纤纤端出射光场的干涉特性，建立了二维光纤干涉的理论模型在一级近似下，推导了二维光纤干涉光场场强分布的理论表达式讨论了实现二维光纤干涉的相关条件，并用二维傅里叶变换方法。
The output optical field interference characteristics formed by the ends of three HiBi single mode fiber is analyzed in this paper.We have established a simple theory model of two dimensional fiber optic interference.Under the condition of first order approximation,the intensity distribution formula of the two dimensional fiber optic interference field is deduced.The spatial frequency properties of the interference optical pattern are analyzed by two dimensional Fourier transformation method.Finally,related experiment results are given.
