Abstract: Aspects of the disclosed apparatuses, methods, and systems provide enhanced display of images for personal wearable display devices. The display systems include various system components to implement one or more of: re-directing the maximal brightness of a display device towards the center of the eye-box of a user; selectively narrowing the viewing angle of light emitted by the display device; and by spatially optimizing the backlight of the display device based on the specification of the wearable optical system thereby optimizing and/or maximizing the amount of light entering the eye for a range of gaze rotation of a user of the wearable display system. In one example, the following description provides a display device including a light optimizing or directing layer. The light optimizing layer includes one or more films that optimize the amount of light directed to the eye box of a user of the wearable display system.

Abstract: A system to provide views of virtual content in an interactive space, e.g., an augmented reality environment, may comprise one or more of a light source, directional control device, variable power lens, beam steering device, optical element, and/or one or more physical processors. A light source may generate collimated light rays in accordance with virtual content to be perceived within a three-dimensional light field. A directional control device may controllable adjust direction of travel of collimated light rays toward a beam steering device. A variable power lens may be positioned to receive collimated light rays between a light source and a directional control device. A beam steering device may be configured to direct collimated light rays to locations on an optical element. An optical element may be configured to reflect collimated light rays in a focal plane of a perceived three-dimensional light field.

Abstract: High performance lens system designs are described. The lens system has four lens groups, is made entirely of spherical lens elements, and, includes selected lens elements made of materials with high refractive index and Abbe numbers and coefficient of thermal expansion that provide stable high performance across wide and rapid temperature changes. Group descriptions and parametric equations enable creation of designs having fields of view ranging from 50 to 150 degrees.

Abstract: A light source module includes a light source, a paraboloid reflector and an aspheric lens. The light source is used for generating a first light. The paraboloid reflector is used for reflecting the first light beam to form a second light. The aspheric lens is used for converging the second light. The aspheric lens includes an aspheric incident surface and an emergent surface. The aspheric incident surface is used for converging the second light beam into a third light, and the emergent surface is used for converging the third light. The emergent surface includes two aspheric curved surfaces configured symmetric to an optical axis of the aspheric lens.

Abstract: A light source module comprises a light source, an elliptical reflector and a secondary reflector. The light source is used for generating a beam. The elliptical reflector is used for reflecting and converging the beam, the elliptical reflector has a first focus and second focus, and the center of the light source is located on the first focus. The secondary reflector is used for reflecting the beam to the elliptical reflector. A distance between the first focus and the second focus is X, and a distance between the first focus and the center of the elliptical reflector is Y, and X, Y satisfy Y??0.0012*X2+0.3728*X?6.8512.

Abstract: A lamp module comprises a light source, a main reflector and an elliptical sub-reflector. The light source has a first arc and a second arc. The distance between the first arc and the second arc is an initial arc gap, and the light source is used for generating a light beam. The main reflector is used for reflecting the light beam and has a central axis, and the light source is disposed on the central axis. The elliptical sub-reflector is used for reflecting the light beam to the main reflector. The elliptical sub-reflector has a first focus and a second focus, a center of the light source is positioned on a long axis of the elliptical sub-reflector and between the first focus and the second focus, and a distance between the first focus and the second focus is larger than the initial arc gap.
