Abstract
A near-eye optical system, for receiving an image beam, includes an optical waveguide, configured to expand the image beam in a direction, and including a near-eye surface and a structure surface. The structure surface includes a light incident area and is opposite to the near-eye surface. The light incident area is located in a transmission path of the image beam. A plurality of reflective inclined surfaces are disposed on the structure surface and located at one side of the light incident surface and arranged along the direction. The structure surface is sequentially divided into the light incident area and a plurality of optical areas along the direction. A line number density of the reflective inclined surfaces in the optical area closest to the light incident area in the direction is less than a line number density of the reflective inclined surfaces in the optical area furthest from the light incident area in the direction.
