摘要： A method of designing lenses includes defining a material having an inside reflective surface spanning an area, and providing an optical design algorithm which defines a plurality of oxels across the area. Each oxel has a plurality of sub-elements including a center sub-element and a plurality of neighboring sub-elements. Based on a defined optical prescription for the inside reflective surface, an optically corrected reference 3D surface is calculated for each oxel having spherical and cylindrical corrections relative to a spherical contour which spans a predetermined field of view (FOV) with respect to a single (common) predetermined reference point. A position of at least a first of the sub-elements for each of the oxels is moved to approach respective final 3D positions on the optically corrected reference 3D surface, where the moving is constrained to be along an individual line connecting each of the first sub-elements to the single predetermined reference point.

摘要： A wearable display system has a first lens sub-assembly defining a first optical path and a second lens sub-assembly defining a second optical path. The first and second lens sub-assemblies are disposed in a frame in respective first and second lens-holding sub-assemblies. The frame also has a device holder configured to maintain a display of a device in the first and second optical paths. The display can be maintained within a predetermined range of distances and angles with respect to the first and second lens sub-assemblies. This arrangement permits the display, such as, for example, a smartphone display, independently to provide a specific image to each eye of a user. For example, different images can be independently provided to each eye from different portions of a common display, thereby enabling the user to perceive a three-dimensional image.

摘要： A lens includes a material spanning an area and providing an inside reflective three-dimensional (3D) surface. The reflective 3D surface is defined by a plurality of reflective optical elements including a first reflective optical element and at least a second reflective optical element that each include a sub-element set including a center sub-element (CS) and a plurality of neighboring sub-elements. The plurality of reflective optical elements each have their own non-overlapping optical center axis; and a cylindrically bent spherical surface. The cylindrically bent spherical surface is defined by the neighboring sub-elements in each reflective optical element being located at different 3D points so that the reflective optical elements relative to at least one neighboring reflective optical element provides different values of spherical curvature and different values of cylindrical axis orientation. Each of the plurality of reflective optical elements can provide a different optical power for correction of astigmatism.

摘要： A head-mounted display (HMD) apparatus comprising at least one optical system, each optical system comprising a lens having a reflective optical surface and an HMD device associated with and distanced from the reflective optical surface. The HMD device comprises a substrate having horizontal and/or vertical convex curvatures having a curved geometric profile which continuously curves with smooth transitions in horizontal and/or vertical dimensions. The curved profile is dimensioned to curve around a temple of a wearer and extend in a direction toward an ear of a wearer. The substrate comprising a plurality of pixel elements arranged along the horizontal convex curvature and being controlled to selectively radiate light representative of computer-generated content (CGC) to the associated reflective optical surface such that those selected pixel elements for display emanate rays of the light for subsequent reflection from the reflective optical surface toward a respective one eye of the wearer.

摘要： A curved Fresnel lens is provided. The Fresnel lens includes a grooved surface and a smooth surface. The grooved surface includes a plurality of concentric sloped facets and a plurality of concentric draft facets. Pairs of concentric draft facets and concentric sloped facets form a plurality of concentric grooves in the grooved surface. The concentric sloped facets are configured to focus light toward an eye of a nominal user. At least some of the concentric draft facets are congruent with conical surfaces of respective imaginary light cones that have corresponding vertices that originate from respective focal points, wherein each imaginary light cone extends through the Fresnel lens at an angle based in part on an index of refraction of the Fresnel lens and extends beyond the grooved surface into free space.
