Abstract

一种光学系统(10)和包括光学系统(10)的近眼显示装置(100)。光学系统(10)包括用于发出图像光(IMG)的显示屏(12)、用于将图像光(IMG)分成偏振态与传播方向均不同的第一偏振图像光(PIMG)和第二偏振图像光(SIMG)的偏振分光器(14)、用于将第一偏振图像光(PIMG)投射到右眼的第一偏振折返系统(16)和用于将第二偏振图像光(SIMG)投射到左眼的第二偏振折返系统(18)。光学系统(10)和近眼显示装置(100)由于采用偏振分光器(14)来起偏，起偏后的第一偏振图像光(PIMG)和第二偏振图像光(SIMG)可以分别用于第一偏振折返系统(16)和第二偏振折返系统(18)，提高了光线的利用率。
