OPTICAL WAVEGUIDE SYSTEM AND AUGMENTED REALITY DEVICE

Abstract: an optical waveguide system and an augmented reality device are disclosed. the optical waveguide system comprises an optical waveguide and a grating disposed on a surface of the optical waveguide, the grating comprises a plurality of cell arrays each having a parallelogram shape, such that one incident light beam incident on the grating is diffracted into two diffracted light beams, and angle between components of one diffracted light beam and the other diffracted light beam on a plane of the grating and a component of the incident light beam on the plane of the grating are not equal. the optical waveguide system including the grating can be combined in more flexible forms, for improving the lighting efficiency, reducing and maintaining a smaller volume of the waveguide lens etc., and the appearance of the waveguide system can also be changed more freely, to meet the preferences of different consumers.
