摘　　要：提出了一种模拟薄膜法布里-珀罗滤光片中反射光束分裂现象的方法.根据反射率曲线,简单解释了产生这个现象的原因.实验上制备了薄膜法布里-珀罗滤光片,观察和测量了反射光束分裂的现象,理论计算基本与实验结果符合.A numerical method to simulate the splitting of the reflected Gaussian beam in the thin-film Febry-Perot filter is described. The splitting can be simply explained by studying the reflection curve. The thin-film Febry-Perot filter has been fabricated by coating TiO2 and SiO2 on glass. The reflected beam splitting phenomenon is observed and measured in practice. The theoretical result is in accord with the experimental result.
