Compact optical device for augmented reality having straightly-arranged optical structure, and method for manufacturing optical means

Abstract

The present invention provides a compact optical device for augmented reality, the compact optical device including: an optical means configured to transmit at least part of real object image light therethrough toward the pupil of a user's eye; a first reflective means embedded and disposed inside the optical means, and configured to transfer augmented reality image light, which is image light corresponding to an image for augmented reality output from an image output unit, to a second reflective means; and the second reflective means including a plurality of reflective units embedded and disposed in the optical means to transfer the augmented reality image light, transferred from the first reflective means, to the pupil of the user's eye by reflecting the augmented reality image light toward the pupil; wherein the optical means has first and second surfaces, and a method for manufacturing an optical means used in the same.
