发明名称 Polarizing splitter device and application to a system for illuminating a liquid-crystal screen
摘要 A polarizing splitter device includes a double prism having an entry face for receiving a beam of unpolarized light, a polarizing splitter transmitting the polarized light in a first polarization direction, and reflecting the light polarized in a second polarization direction. The double prism also has a reflection face provided with a mirror receiving the light reflected by the polarizing splitter as well as an exit face for receiving and transmitting the light transmitted by the polarizing splitter and reflected by the mirror.
