Abstract:
Techniques related to a see-through optical system are disclosed. According to one aspect of the techniques, the optical system includes a lens unit for enlarging an image light displayed on a display panel, a horizontal light guide includes an inclined plane of a sawtooth shape to totally reflect the enlarged image light and expand an exit pupil distance along a horizontal direction, a vertical light guide placed under the horizontal light guide to totally reflect the enlarged image light transferred from the horizontal light guide to expand the exit pupil distance in a vertical direction. Optionally, a compensation prism for reflecting the image light with the exit pupil distance expanded in both horizontal and vertical directions is used.

Claim (Index 5):
The optical system according to  claim 4 , wherein a distance c between the two adjacent sawteeth is so defined that part of the enlarged image light is reflected and another part of the enlarged image light is totally reflected and continuously propagated for expansion of the exit pupil distance along the horizontal direction.
