Abstract: An optical apparatus for a see-through near-to-eye display includes a diffractive optical combiner, one or more refractive correction lenses, and a diffractive correction element. The diffractive optical combiner has an eye-ward side and an external scene side and includes a reflective diffraction grating that is at least partially reflective to image light incident through the eye-ward side and at least partially transmissive to external scene light incident through the external scene side. The one or more refractive correction lenses are disposed in an optical path of the image light to aid in pre-correcting aberrations induced in the image light after reflection off of the diffractive optical combiner. The diffractive correction element is disposed in the optical path of the image light to pre-compensate for lateral color aberrations induced in the image light after reflection off of the diffractive optical combiner.

Abstract: A head-wearable display includes a collimated light source, a beam steering mechanism, and a synchronization controller. The collimated light source selectively emits collimated light. The beam steering mechanism is optically coupled to receive the collimated light and angularly scans the collimated light between beam steering states that each redirect the collimate light to a different angular direction along at least one angular dimension. The beam steering mechanism is coupled to scan the collimated light across an eyebox. The synchronization controller is coupled to the collimated light source and the beam steering mechanism to synchronize selective emission of the collimated light from the collimated light source with the beam steering states of the beam steering mechanism to repetitiously draw an image in the eyebox.

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.

Abstract: An eyepiece for a head wearable display includes a curved lightguide component, a curved see-through component, an output coupler, and a prescription layer. The curved lightguide component guides display light received at an input region and releases the display light along an eye-ward direction in a viewing region. 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 at least partially transmissive to ambient light incident through a world-facing side such that the viewing region is see-through. The curved see-through component is mated to the world-facing side of the curved lightguide component. The prescription layer has a first side mated to an eye-facing side of the curved lightguide component and a second side having a curvature that introduces prescriptive lensing to both the ambient light and the display light.

Abstract: A display apparatus includes a transparent substrate having first and second sides, an array of LED micro-display panels, and an array of collimating reflectors. The LED micro-display panels are disposed within the transparent substrate between the first and second sides and oriented to emit sub-image portions of a display image towards the first side. The collimating reflectors are disposed within the transparent substrate between the first side and the array of LED micro-display panels. The collimating reflectors are aligned with the LED micro-display panels to reflect the sub-image portions back out the second side of the transparent substrate. The LED micro-display panels are offset from the collimating reflectors to expand the sub-image portions prior to reflection by the collimating reflectors.

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 optical apparatus includes a first optical element having an eye-ward facing surface and an external world facing surface substantially opposite of the eye-ward facing surface. The optical apparatus also includes a diffractive optical element (“DOE”) disposed to substantially follow a curvature of the eye-ward facing surface of the first optical element. The DOE includes a partially reflective diffraction grating configured to direct a portion of image light in an eye-ward direction where the image light is incident through an eye facing side of the DOE. The curvature of the eye-ward facing surface of the first optical element has an optical power configured to collimate the image light within an eyebox sized area.
