COMPACT TYPE OPTICAL DEVICE FOR AUGMENTED REALITY WHICH CAN PREVENT GHOST IMAGES WITH WIDE FIELD OF VIEW

摘要

The present invention relates to an optical device for a compact augmented reality having a ghost image blocking function and a wide viewing angle, comprising: optical means for transmitting at least a portion of real object image light toward a pupil of a user's eye; a first reflection unit disposed inside the optical unit and transmitting the augmented reality image light that is image light corresponding to the image for augmented reality emitted from the image output unit to the second reflection unit; and a second reflector disposed inside the optical means and providing an image for augmented reality to the user by reflecting and transmitting the augmented reality image light transmitted from the first reflector toward the pupil of the user's eye, The optical means has a first surface on which the real object image light is incident, and a second surface on which the augmented reality image light transmitted through the second reflection unit and the real object image light are emitted toward the pupil of the user's eye, the The augmented reality image light emitted from the image output unit is transmitted to the first reflecting unit through the inside of the optical means or is totally reflected from the inner surface of the optical unit and transmitted to the first reflecting unit, and the first reflecting the augmented reality image light The reflecting surface of the reflecting unit is disposed to face the first surface of the optical means on which the actual object image light is incident, and the second reflecting unit reflects the augmented reality image light transmitted from the first reflecting unit, respectively, to the pupil of the user. Consists of a plurality of reflective modules disposed inside the optical means to transmit to, and the plurality of reflective modules constituting the second reflective unit increases the distance from the first reflective unit to the pupil of the augmented reality image light. It provides a compact optical device for augmented reality having a ghost image blocking function and a wide viewing angle, characterized in that it is disposed inside the optical means so as to be closer to the second surface of the optical means emitting toward.
