Abstract
This invention relates to a head mounted image display apparatus to be mounted on a head portion of an observer. The apparatus is constructed by image generation means for displaying an image by radiating light and an optical system which has a plurality of optical elements for guiding light from said image generation means to a pupil of the observer, wherein, of said plurality of optical elements, a first decentered curved surface mirror based on an ellipsoidal surface and a second decentered curved surface mirror based on a hyperboloidal surface are arranged in turn from the pupil side of the observer, said first decentered curved surface mirror has a first focal point at a predetermined pupil position of the observer, and a second focal point at a focal point position of said second decentered curved surface mirror.
