Claim 1:
2. The diffractive optical waveguide of claim 1, wherein the first coupling-out region and the second coupling-out region are mirror-symmetric with respect to a central axis of the waveguide substrate, and the central axis of the waveguide substrate passes through the center of the coupling-in region and is perpendicular to the center line; and/or
the waveguide substrate is mirror-symmetric with respect to the central axis; and/or
a distance between the center of the coupling-in region and the center of the first coupling-out region is equal to a distance between the center of the coupling-in region and the center of the second coupling-out region.
