Abstract: A method of fabricating an optical aperture multiplier is provided. A slice and a first optical structure are obtained. The slice has external faces including a pair of parallel faces, and a first plurality of partially reflective internal surfaces oblique to the pair of parallel faces. The first optical structure has external surfaces including a planar coupling surface, and a second plurality of partially reflective internal surfaces oblique to the coupling surface. The slice is optically coupled with the first optical structure such that one of the faces of the pair of parallel faces is in facing relation with the coupling surface to form a second optical structure. At least one optical aperture multiplier is sliced from the second optical structure by cutting the second optical structure through at least two cutting planes perpendicular to the coupling surface. The optical aperture multiplier is preferably part of a near eye display augmented reality system.

Abstract: Disclosed herein is a system for producing a composite prism having a plurality of planar external surfaces by aligning and bonding two or more prism components along bonding surfaces thereof, the system includes: an infrastructure configured to bring the bonding surfaces of the first prism component and the second prism component into close proximity or contact; a controllably rotatable mechanical axis configured to align at least one first surface of the first prism component and at least one second surface of the second prism component; a light source configured to project at least one collimated incident light beam on the at least one first surface and the at least one second surface; one or more detectors configured to sense light beams reflected from the first and second surfaces; a computational module configured to determining an average actual relative orientation between the at least one first surface and the at least one second surface based on the sensed data and if a difference between the weighted average actual relative orientation and an intended relative orientation between the at least one first surface and the at least one second surface is below an accuracy threshold, determine a correction angle for the controllably rotatable mechanical axis, wherein one or more of the prism components are transparent or semi-transparent.

Abstract: An optical device has an LOE formed from a light-transmitting material having a first refractive index. A pair of parallel major external surfaces of the LOE guide image illumination within the LOE by TIR. At least one optical coupling configuration of the LOE deflects a proportion of the image illumination that is guided within the LOE by TIR. An optical material includes at least one transparent material directly attached to the LOE at least at the major external surfaces so as to be in direct contact with the major external surfaces and so as to at least partially encapsulate the LOE. The optical material has a second refractive index less than the first refractive index to maintain conditions of TIR at the major external surfaces. In certain embodiments, the TIR-guided image illumination is incident to the major external surfaces at angles greater than a critical angle, including shallow angles.

Abstract: An optical device has a light-transmitting substrate, an optical coupling-out configuration, and an optical arrangement. The light-transmitting substrate has at least two major surfaces and guides light by internal reflection between the major surfaces. The optical coupling-out configuration couples the light, guided by internal reflection, out of the light-transmitting substrate toward an eye of a viewer. The optical arrangement is associated with at least one of the two major surfaces, and has a first optical element and a second optical element. The optical elements are optically coupled to each other to define an interface region associated with at least a portion of the coupling-out configuration. The interface region deflects light rays that emanate from an external scene that are incident to the optical arrangement at a given range of incident angles.

Abstract: A light-guide device includes a light guiding element (13) with a number of faces, including two parallel faces (26), for guiding light by internal reflection. A transparent optical element (19) has an interface surface for attachment to a coupling surface (14) of the light guiding element, and is configured such that light propagating within the transparent optical element passes through the interface surface and the coupling surface (14) so as to propagate within the light guiding element (13). A non-transparent coating (15) is applied to at least part of one or more faces of the light guiding element (13), defining an edge (17) adjacent to, or overlapping, the coupling surface (14) of the light guiding element (13). A quantity of transparent adhesive is deployed between the coupling surface and the interface surface so as to form an optically transmissive interface. An overspill region 31 of the adhesive extends to, and overlaps, the edge (17).

Abstract: A stack has first and second faces and multiple LOEs that each has two parallel major surfaces and a first plurality of parallel internal facets oblique to the major surfaces. A first block has third and fourth faces and a second plurality of parallel internal facets. The first block and the stack are bonded such that the second face joins the third face and the first and second facets are non-parallel, forming a second block. The second block is cut at a plane passing through the first face, forming a first structure having an interfacing surface. A third block has fifth and sixth faces and a plurality of parallel internal reflectors. The third block and the first structure are bonded such that fifth face joins the interfacing surface and the internal reflectors are non-parallel to all the facets, forming a second structure. Compound LOEs are sliced-out from the second structure.
