Document Type and Number:
WIPO Patent Application WO/2020/166785
Kind Code:
A1
Abstract:
The present invention relates to an augmented reality optical device capable of providing an augmented reality image at close range, and provides an augmented reality optical device capable of providing an augmented reality image at close range, comprising: an optical means for transmitting at least a part of image light emitted from a real object toward the pupil of a user's eye, and reflecting, at least once on the inner surface thereof, image light that corresponds to an augmented reality image emitted from an image emission unit and transmitting same to an optical element; and at least one optical element which is disposed inside the optical means, and which provides an augmented reality image to the user by transmitting, toward the pupil of the user's eye, the image light corresponding to the augmented reality image transmitted through the optical means, wherein the optical means has a first surface on which the image light emitted from the real object is incident and a second surface from which the image light corresponding to the augmented reality image transmitted through the optical element is emitted, and the first surface and the second surface have an inclination angle (θ) so as not to be parallel to each other.
