ABSTRACT:
The image observation apparatus includes a first image-forming element and a second image-forming element each of which forms an original image, and an optical system configured to introduce light fluxes from the first and second image-forming elements to an exit pupil position of the optical system where an eye of an observer is placed. The optical system includes an optical surface as a single surface that reflects the light flux from the first image-forming element and transmits the light flux from the second image-forming element. The first image-forming element and the second image-forming element respectively form a first original image and a second original image that correspond to different viewing fields from the exit pupil position. The apparatus combines plural original images to enable observation of one combined image and that can suppress generation of light scattering.
