Abstract: A wearable device for augmented reality applications including an image generation engine to generate multiple light rays forming an image, and an eyepiece including a display to project the image to a user for an augmented reality application, is provided. The eyepiece includes a planar waveguide configured to transmit the light rays from the image generation engine. The wearable device also includes at least one optical element configured to couple the light rays into, and to provide the light rays from, the planar waveguide and through an eyebox limiting a volume that includes a pupil of the user, and a user-functional portion of the eyepiece including the at least one optical element, the user-functional portion shaped according to a pre-selected format that is aesthetically appealing to an onlooker when the immersive reality device is worn by a user.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling element located at the input end for coupling light into the waveguide body, and an output coupling element located at the output end for coupling light out of the waveguide body, where the waveguide body includes an organic solid crystal. The organic solid crystal may be a single crystal having principal axes rotated with respect to the dimensions of the waveguide body. Such an optical element may have low weight and exhibit good color uniformity while providing polarization scrambling of the guided light.

Abstract: An optical device for a head-mounted display device includes a first partial reflector and a second partial reflector positioned relative to the first partial reflector so that the second partial reflector receives first light transmitted through the first partial reflector and reflects at least a portion of the first light toward the first partial reflector as second light. At least a portion of the second light is reflected by the first partial reflector as third light, and at least a portion of the third light is transmitted through the second partial reflector. At least one of the first partial reflector or the second partial reflector includes a reflective holographic element.
