格兰－付科棱镜光强透射比曲线波动成因的研究
Study of transmittance fluctuation of Glan-Foucault prisms
摘要
Abstract
With continuous change of the incidence angle , the transmittance of a Glan-Foucault prism fluctuates a lot . In order to suppress such fluctuation , experiments were carried out for measurement of the transmittance of the Glan-Foucault prism based on a polarized light experimental system .The transmittance was simulated under the assumption that there was multiple beam interference between the prism air gaps .Simulation results and experimental results matched very well.The relative quantitative reason of the transmittance fluctuating with the incidence angle was put forward for the first time.Two methods were proposed to inhibit the fluctuation .The results showed that the reason of fluctuation is the strengthened or weakened multiple beam interference induced by the change of path difference of interference beam between the air gap with the rotation of the stepping motor with the prism as depolarizer .The fluctuations are stronger just because the transmitted beam for the Glan-Foucault prisms is s component on the incident plane which has greater reflectance .The study is helpful for suppressing the transmittance fluctuation of a Glan-Foucault prism.关键词
