Title:
COMPACT AUGMENTED REALITY OPTICAL DEVICE USING TOTAL REFLECTION
Document Type and Number:
WIPO Patent Application WO/2022/014875
Kind Code:
A1
Abstract:
The present invention provides an augmented reality optical device comprising: an optical means through which real object image light passes toward a pupil; a first reflection part disposed in the optical means and transferring, to a second reflection part, augmented reality image light emitted from an image emission part; and the second reflection part disposed in the optical means, and reflecting and transferring, to the pupil, the augmented reality image light, transferred from the first reflection, wherein: the optical means has a first surface on which the real object image light is incident, and a second surface from which the augmented reality image light and the real object image light are emitted toward the pupil; a reflection surface, which reflects the augmented reality image light of the first reflection part, is disposed toward the first surface of the optical means; the augmented reality image light emitted from the image emission part is totally reflected from the first surface of the optical means and transferred to the first reflection part, is reflected by the first reflection part and emitted toward the first surface of the optical means, and is totally reflected from the first surface of the optical means and transferred to the second reflection part; and the second reflection part disposed on the inner surface of the optical means so as to reflect and transfer, to the pupil, the augmented reality image light totally reflected and transferred from the first surface.
