一个有效减小透射式液晶后续光学系统口径的方法

A method to minish the aperture of the optical system with through transmission LCD

由于液晶结构的特殊性 ,在液晶 (尤其是透射式液晶 )的后续光学系统设计中 ,要求有比较小的F数 ,这给光学系统设计带来了困难。提出了一个在液晶平面上添加场镜的方法 ,可以有效地降低对后续光学系统口径的要求 。

Because of the idiosyncratic structure of the liquid crystal, small F number is recommended in the design of the optical system in which a through transmission LCD is used It is handicap to the design and manufacture A new method to add a planoconvex lens to the LCD plane is dealt with Using the lens, the limit to the aperture of the optical system can be efficaciously reduced
