摘要： An optical system attaining a nearly double resolving power in spite of one projector and also eliminating a convergence device is provided. The system includes an 1:1 relay lens 35 in place of a projector lens of a RGB split-combine projection system 102, and a quarter-wave plate 51 for P-S polarization separation. In operation, once-modulated RGB composite light is divided into a P-polarized light and a S-polarized light by a PS separation wire grid 52. The S-polarized light is modulated by a luminance signal Y1 at a Y1 device 63. The P-polarized light is modulated by a luminance signal Y2 at a Y2 device 58. The lights modulated by the Y1/Y2 devices 63, 58 are combined with each other at a PS composite wire grid 66 to project a synthetic light on a screen.
摘要翻译：尽管是一台投影仪，并且也省去了会聚装置，但是提供了几乎是两倍分辨率的光学系统。该系统包括1：1中继透镜35代替RGB分离合成投影系统102的投影透镜和用于P-S偏振分离的四分之一波片51。在操作中，一次调制的RGB合成光被PS分离线栅格52分成P偏振光和S偏振光.S偏振光在Y1器件63处由亮度信号Y1调制。在Y2器件58处通过亮度信号Y2调制P偏振光。由Y1 / Y2器件63,58调制的光在PS复合线栅66处彼此组合，以将合成光投影到屏幕上。

摘要翻译：提供尽管有一台投影机达到几乎双重分辨率的光学系统，并且还消除了会聚装置。该系统包括1：1中继透镜35，代替RGB分离组合投影系统102的投影透镜，以及用于P-S偏振分离的四分之一波片51。在操作中，通过PS分离线栅52将一次调制的RGB复合光分为P偏振光和S偏振光.S偏振光由Y1器件63处的亮度信号Y1调制。 P偏振光在Y2装置58处由亮度信号Y2调制。由Y1 / Y2装置63,58调制的光在PS复合线栅66处相互组合，以将合成光投射在屏幕上。
