Abstract
This invention velates to an image displaying apparatus which includes a plurality of image displaying devices for displaying respective display images on display surfaces thereof, reflecting surfaces provided in correspondence to the respective image display devices, each for reflecting a light beam from the corresponding image display device and an optical system for guiding light beams from the plurality of reflecting surfaces to a pupil of an observer.
Claims12
An image displaying apparatus comprising:
- a plurality of image displaying means for displaying respective display images on display surfaces thereof;
- a relay optical system for forming intermediate images of the respective display images, said relay optical system having optical systems provided in correspondence to said respective image displaying means, said optical systems having respective curved reflecting surfaces positioned so that adjacent-side principal rays of adjacent display images of said plurality of display images travel in a same optical path after being reflected by said plurality of reflecting surfaces;
- and
- a common optical system for guiding light beams from said plurality of reflecting surfaces to a pupil of an observer.
