(EN) DISPLAY ILLUMINATION OPTICS
(FR) SYSTÈME OPTIQUE D'ÉCLAIRAGE D'AFFICHAGE
Abstract
(EN)
Aspects of embodiments pertain to a display illumination optics for illuminating an image display device of an image generation apparatus, the display illumination optics comprising: a source illumination distributor that includes an illumination waveguide having a front surface and a back surface opposite the front surface and configured to internally direct light along a main direction, wherein the illumination waveguide is configured to distribute the luminance of input illumination light along the main direction of the display illumination optics to obtain, along the main direction, output illumination light of desired luminance.
