Optical device for augmented reality capable of providing image for augmented reality having close distance

Abstract

The present invention provides an optical device for augmented reality, the optical device including: an optical means configured to transmit at least part of image light therethrough toward the pupil of an eye of a user, and to transfer image light corresponding to an image for augmented reality to at least one optical element by reflecting the image light from the inner surface thereof at least once; and the optical element disposed inside the optical means, and configured to provide the image for augmented reality to the user by transferring the image light, corresponding to the image for augmented reality transmitted through the optical means, toward the pupil of the user; wherein the optical means includes a first surface and a second surface, and the first surface and the second surface have an inclination angle with respect to each other so as not to be parallel to each other.
