Optical system for head-mounted display

Abstract

An optical system for a head-mounted display in which image rays provided from a display device are divergent to form and provide an enlarged image is configured so that first and second lenses are sequentially disposed from an object along an optical axis and provide the enlarged image on an image plane, and angles of principal rays are gradually increased from the optical axis toward the edge of the image plane. Thus, as the angles of principal rays are increased, an angle of view is improved to provide a large screen so that it is possible to appreciate a vivid image due to an increase in the sense of presence and the degree of involvement. The entire size of the optical system can be reduced. The head-mounted display can be made compact and lightweight.
