Transmittance spectrum in the liquid crystal spectro-polarimetric system
摘要
Abstract
In order to analyze the transmittance property of the liquid crystal spectro-polarimetric system,the research simulates the distribution of transmittance spectrum in the visible spectrum.The transmittance spectrum of liquid crystal polarizer is obtained based Berreman matrix.Meanwhile,by combining Lyot liquid crystal tunable filter and liquid crystal variable retarder,the transmittance spectrums of system are investigated with different polarization states in normal incidence and oblique incidence.The conclusion is that spectrum of system reaches its vale in 540～680 nm at normal incident angle,but in 520～640 nm at oblique incident angle.Spectral blue shift occurs in the oblique incidence relative to the normal incidence.When different incident light propagating through system,transmittance of circular polarized light is approximately 0 at vale,hut linearly polarized light is around 0.25.By investigating the transmittance spectrum of the liquid crystal spectro-polarimetric system,the constitute forms of incident light are analyzed which can lay the foundation for measuring property enhancement and researching further.关键词
