Abstract:
A waveguide comprises a first surface and a second surface. The second surface comprises a first plurality of grating structures. The waveguide is configured to guide an in-coupled light beam to undergo total internal reflection between the first surface and the second surface. The grating structures are configured to disrupt the total internal reflection to cause at least a portion of the in-coupled light beam to couple out of the waveguide from the first surface, the portion of the in-coupled light beam coupled out of the waveguide forming out-coupled light beams. The waveguide further comprises a reflective layer disposed on the second surface and covering the first grating structures.

Claim (Index 26):
The light projecting system of  claim 22 , wherein:\n the second surface is in an x-y plane; the in-coupled light beam propagates inside the waveguide substantially along the x-direction of the x-y plane; the out-coupled light beams propagate substantially along a z-direction normal to the x-y plane; the first grating structures are distributed in the x-y plane with respect to corresponding (x, y) positions; the first grating structure is each associated with a grating depth, a duty cycle, a period, and an orientation in the x-y plane with respect to the z-direction; the first grating structures at different x-direction positions have at least one of different grating depths or different grating duty cycles; the first grating structures at different x-direction positions have different periods; and the first grating structures at different y-direction positions have different orientations.
