Abstract:
A light-weight and ultrathin waveguide optical element having a large field of view includes two or more layers of waveguide plates provided to be overlapped with each other. Within each layer of the waveguide plate are included multiple reflective surfaces with different reflectivity, such that light transmitted through the waveguide plate has a substantially uniform distribution of intensity in a predetermined area when exiting from the waveguide plate. The waveguide optical element is ultrathin such that it can be directly mounted into a spectacle frame. Use of the waveguide optical element with a projection optical assembly can improve user experience as well as display effect with good contrast.

Claim (Index 2):
The waveguide optical element according to  claim 1 , wherein there are a plurality of the partially reflective surfaces inside each of the waveguide plates, and numbers of the partially reflective surfaces inside each of the waveguide plates are identical or different.
