Document Type and Number:
WIPO Patent Application WO/2021/080342
Kind Code:
A1
Abstract:
The present invention provides an augmented reality optical device having a ghost image blocking function, the augmented reality optical device comprising: an optical means for transmitting at least a part of actual object image light toward the pupil of a user's eye, wherein the actual object image light is image light emitted from an actual object; a first reflecting unit arranged in the optical means and transferring augmented reality image light to a second reflecting unit, wherein the augmented reality image light is image light that corresponds to an image for augmented reality and is emitted from an image emitting unit; and the second reflecting unit arranged in the optical means and reflecting and transferring the augmented reality image light from the first reflecting unit toward the pupil of the user's eye so as to provide the user with the image for augmented reality. The optical means has a first surface onto which the actual object image light is incident and a second surface through which the augmented reality image light transferred from the second reflecting unit and the actual object image light are emitted toward the pupil of the user's eye. The augmented reality image light is transferred to the first reflecting unit through the inside of the optical means or is totally reflected from an inner surface of the optical means and transferred to the first reflecting unit. A reflecting surface of the first reflecting unit for reflecting the augmented reality image light is arranged toward a direction in which the augmented reality image light is incident.
