Optical device for augmented reality having refractive space

Abstract

The present invention provides an optical device for augmented reality having a refractive space, the optical device including: a first optical element configured to transfer virtual image light to a second optical element; the second optical element configured to transfer the virtual image light toward the pupil of an eye of a user; an optical means configured such that the first optical element and the second optical element are embedded therein; and a refractive space formed inside the optical means; wherein the refractive space has a first surface and a second surface; and wherein the virtual image light output from the image output unit enters the first optical element through the second surface of the refractive space, is reflected by the first optical element and then output through the second surface of the refractive space, and is then transferred to the second optical element.
