1. An optical apparatus comprising:
- first optical means for controlling a visual image to a first eye of a viewer consisting of(a) lens means having an optical axis;
(b) display means for displaying a video image through said lens means on said optical axis;
(c) beam splitter means for splitting a beam representing a visual image, said beam splitter means being arranged at an angle of substantially 45 degrees on said optical axis and located after said lens means;
(d) shutter means disposed in front of said beam splitter means for selectively controlling transmission of an image therethrough from the optical apparatus surrounding to said first eye of the viewer, wherein said video image displayed on said display means appears as a virtual image superimposed upon said image from the surroundings when said first eye of the viewer views said video image from behind said beam splitter means;
second optical means for controlling a visual image to a second eye of the viewer consisting of sub-shutter means for selectively controlling transmission of an image therethrough from the optical apparatus surroundings to said second eye of the viewer; and
shutter control means for controlling image transmission operations of said shutter means and said sub-shutter means.

Abstract
An optical apparatus using a display device is comprised of a lens system having an optical axis, a display device for displaying a video image on the optical axis, a beam splitter for splitting information of visual image, the beam splitter being formed so as to incline an angle of about 45 degrees relative to the optical axis and located under the lens system, and a shutter device disposed in front of the beam splitter for controlling transmission of image from the surrounding, wherein the video image is shown as a virtual image with the image from the surroundings when viewer peeps the video image from the back of the beam splitter.
