Image display apparatus and optical system |
摘要 |
<p>An image display apparatus includes a light source for supplying illumination light, a reflection type display element for modulating the illumination light into image light by reflecting the light, an illumination optical system for guiding the illumination light to the reflection type display element, and a projection optical system for guiding the image light to an observer. The image light is incident on the projection optical system via at least a portion of said illumination optical system. The projection optical system includes a member for correcting an optical path length difference between rays of the image light caused when the image light is incident on the projection optical system via at least a portion of the illumination optical system. <IMAGE></p> |
