Abstract: An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light to a viewing region offset from a peripheral location and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes a curved lightguide to guide the display light, an eye-ward facing surface that is concave, a world facing surface that is convex and opposite the eye-ward facing surface, and an optical combiner disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide. The optical combiner is partially transmissive to ambient light incident through the world facing surface such that the viewing region is see-through. In some embodiments, a prism is disposed proximate to the input surface to pre-compensate the display light for lateral chromatic aberrations resulting the curved lightguide.

Abstract: An eyepiece for a head wearable display includes a curved lightguide component, an input coupler, and an output coupler. The curved lightguide component guides display light received at an input region peripherally located from a viewing region and emits the display light along an eye-ward direction in the viewing region. The curved lightguide component includes an eye-ward facing surface that is concave and a world facing surface that is convex. The input coupler is disposed at the input region to couple the display light into the curved lightguide component. The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is partially transmissive to ambient light incident through the world facing surface. The display light is guided between the input coupler and the output coupler entirely by total internal reflection.

The curved mirror is positioned to reflect the image light toward an eye-ward side of the optical apparatus. A first curvature of the curved mirror has an optical power configured to focus the image light reflected by the curved mirror within an eyebox sized area. The transparent microdisplay is disposed between the curved mirror and the eyebox sized area.

Abstract: An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light in the viewing region. The light guide component includes an input surface oriented to receive the display light into the light guide component, an eye-ward facing side having a first curvature, a world facing side having a second curvature, a total internal reflection (“TIR”) portion disposed proximal to the input surface to guide the display light using TIR, and a partially reflective portion disposed distal to the input surface to receive the display light from the TIR portion and guide the display light to the viewing region using partial reflections. The first and second curvatures of the eye-ward and world facing sides together operate to adjust the vergence of the display light to virtually displace an image.
