摘要：
An optical system capable of enhancing a specific polarization state of light beam comprises a polarization beam splitter and a polarization state converter. The polarization beam splitter separates an input light beam into a first light beam of first polarization state and a second light beam of second polarization state. The first polarization state is different from the second polarization state. The second light beam is input into the polarization state converter and converted to a third light beam having significantly much more components of first polarization state. The polarization state converter has a configuration providing total reflection or high reflection function. The configuration includes at least one anisotropic optical thin film that is disposed between an incident medium of high refractive index and a medium of low refractive index.
