Title:
AUGMENTED REALITY OPTICAL SYSTEM AND AUGMENTED REALITY GLASSES
Document Type and Number:
WIPO Patent Application WO/2022/143204
Kind Code:
A1
Abstract:
An augmented reality optical system and augmented reality glasses, the augmented reality optical system comprising: a light waveguide (100), a laser module (200) and a galvanometer (300). The light waveguide (100) is provided with an in-coupling zone (11), an out-coupling zone (12) and a transfer zone (13). An angle between the direction of a light beam emitted by the laser module (200) and the plane on which the light waveguide (100) is located is not less than 60 degrees. The laser module (200) is configured for emitting a light beam, the transfer zone (13) is configured for receiving the light beam from the laser module (200) and diffracting the light beam to the galvanometer (300), the galvanometer (300) is configured for scanning and reflecting the light beam to the in-coupling zone (11), the in-coupling zone (11) is configured for coupling the light beam to the light waveguide (100) such that the light beam propagates by total reflection in the light waveguide (100), and the out-coupling zone (12) is configured for coupling the light beam totally reflected by the light waveguide (100) out to a human eye for imaging. By means of the augmented reality optical system and augmented reality glasses, display effects of AR glasses are improved, and internal space is saved.
