Abstract: Embodiments are described of an apparatus including an eyepiece having a front surface, a back surface spaced apart from the front surface, and an edge forming a perimeter of the eyepiece. The eyepiece includes an angled surface to direct light eye-measurement light reflected from an eye into the eyepiece and to direct display light out of the eyepiece to the eye. A first waveguide is formed in the eyepiece and extending from the angled surface to the edge, the first waveguide being optically coupled to a first portion of the angled surface having a first surface treatment. And a second waveguide is formed in the eyepiece and extending from the angled surface to the edge, the second waveguide being optically coupled to a second portion of the angled surface having a second surface treatment.

Abstract: An optical apparatus for a near-eye display includes a microdisplay to emit image light and one or more field lenses positioned to receive the image light from the microdisplay. The one or more field lenses have a combined optical power to form a curved intermediate image. A freeform combiner, having an eyeward side and an external side, is positioned to receive the image light from the one or more field lenses and reflect the image light. A curved intermediate image is formed between the freeform combiner and the one or more field lenses.

Abstract: Implementations are described of an eyepiece for a head wearable display. The eyepiece includes a curved lightguide for guiding display light via total internal reflection between a peripherally-located input surface and a viewing region and an output coupler disposed across the viewing region to redirect the display light towards an eyeward direction for output from the curved light guide. The output coupler has an optical axis and has a set of reflective surfaces that includes at least two individual reflective surfaces to reflect incident display light toward the eyeward direction in at least two different directions relative to the optical axis of the output coupler. Other embodiments are disclosed and claimed.

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 apparatus for use with a head wearable display includes a curved eyepiece for guiding display light received at an input surface peripherally located from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes an optical combiner, an eye-ward facing surface that is concave, a world facing surface that is convex, and a curved lightguide disposed between the eye-ward facing and world facing surfaces to guide the display light via total internal reflections from the input surface to the viewing region. The optical combiner is disposed within the curved eyepiece at the viewing region to redirect the display light towards the eye-ward direction. The optical combiner includes a pattern of reflective elements separated by interstitial regions. The interstitial regions pass ambient light incident through the world facing surface such that the viewing region is partially see-through.
