Abstract: A virtual image display system includes: a light source for projecting an image; a first beamsplitter including a first free-form curved surface; and a second beamsplitter including a second free-form curved surface facing the first free-form surface of the first beamsplitter, in which the first free-form curved surface is separated from the second-free form curved surface of the second beamsplitter by free space, and in which the first beamsplitter and the second beamsplitter are arranged to redirect light emitted from the light source toward a user to form a virtual image.

Abstract: Disclosed is an Augmented Reality (AR) optical waveguide. The AR optical waveguide includes a transparent substrate including a user proximate surface and a user distal surface. The AR optical waveguide also includes a slant etched diffractive grating included on the user distal surface of the transparent substrate. The slant etched diffractive grating includes a refractive index of greater than or equal to 2.0.
