摘要： Three dimensional projection systems may be single projector or multiple projector systems. These 3D projection systems may include a polarization conversion system (PCS). The PCS may be designed for relatively small throw ratios and thus, may be designed to accommodate the small throw ratios. The PCS may include a polarizing beam splitter, a first optical stack, a reflector and a second quarter wave retarder. The first optical stack may include a rotator, a polarizer, a polarization switch and a first quarter wave retarder. The PCS may receive light from a projector and the PBS may direct the light toward the first optical stack. The light may be converted to a different polarization state as it passes through the first optical stack. The converted light may then be re-directed by a reflecting element to the second quarter wave retarder. The second quarter wave retarder may convert linearly polarized light to circularly polarized light.
摘要翻译：三维投影系统可以是单个投影仪或多个投影仪系统。这些3D投影系统可以包括偏振转换系统（PCS）。 PCS可以设计用于相对小的投掷比，因此可以被设计成适应小投掷比。 PCS可以包括偏振分束器，第一光学堆叠，反射器和第二四分之一波长延迟器。第一光学堆叠可以包括旋转器，偏振器，偏振开关和第一四分之一波长延迟器。 PCS可以从投影仪接收光，并且PBS可以将光引导到第一光学堆叠。当光通过第一光学堆叠时，光可以被转换成不同的偏振状态。转换的光然后可以被反射元件重新引导到第二个四分之一波长延迟器。第二四分之一波长延迟器可以将线性偏振光转换成圆偏振光。
