摘要: An exit pupil extender wherein the relative amount of different color components in beam is more consistent with that input beam. In order to compensate for uneven diffracted beam, extender, comprises a plurality layers having additional diffraction gratings so as increase light those lower amount. Additionally, filters disposed between reduce higher
