Abstract:
An optical waveguide, which includes a medium layer and N semi-transmissive, semi-reflective films supported by the medium layer. The semi-transmissive, semi-reflective films are arranged in sequence along a first direction perpendicular to a thickness direction of the medium layer. The orthographic projections of two adjacent semi-transmissive, semi-reflective films on a plane parallel to the thickness direction of the medium layer have an overlap region. A contour of each semi-transmissive, semi-reflective film is a curved surface structure, curved surface structures of the N semi-transmissive, semi-reflective films are N continuous sub-curved surfaces formed by segmenting a same curved surface respectively, a sum of heights of the N sub-curved surfaces is a height of the curved surface, and a concave side of the curved surface structure of each semi-transmissive, semi-reflective film faces towards a same bottom surface of the medium layer.

Claim (Index 10):
The augmented reality device according to  claim 8 , wherein orthographic projections of each of the N semi-transmissive, semi-reflective films on the bottom surface of the medium layer have an overlap region,\n wherein light emitted from the image display apparatus is polarized light, and wherein each of the semi-transmissive, semi-reflective films is a polarization splitting dielectric film, wherein the polarization splitting dielectric film is configured to enable the polarized light impinging thereon to be totally reflected.
