Abstract: An optical system has a hollow mechanical body having first and second ends. An optical assembly has a plurality of optical components arranged in a stack configuration. Each of the optical components has a set of engagement configurations. For each pair of adjacent optical components in the stack configuration, at least some of the engagement configurations of a first optical component in the pair engage with at least some of the engagement configurations of a second optical component in the pair. Some of the engagement configurations of the optical component at a first end of the stack configuration engage with corresponding engagement configurations of the hollow mechanical body at the first end of the hollow mechanical body to position the other optical components of the stack configuration within the hollow mechanical body. An emissive display device is deployed at the second end of the hollow mechanical body.

Abstract: Optical sample characterization facilitates measurement and testing such as transmittance or reflectance at any discrete angle in a full range of angles of light propagation through a coated glass plate having a higher than air index of refraction. A rotatable assembly includes a cylinder having a hollow, and a receptacle including the hollow. The receptacle also contains a fluid having a refractive index matching the refractive index of the cylinder and coated plate. An optical light beam is input normal to the surface of the cylinder, travels through the cylinder, then via the index matching fluid through the coating, the coated glass plate, the fluid, the other side of the cylinder, and is collected for analysis. Due at least in part to the index matching fluid surrounding the coated plate, the plate can be rotated through a full range of angles (±90°, etc.) for full range testing of the coating.

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.

Abstract: A method for producing light-guide optical elements (LOEs) (16, 18, 56, 58) each having a set of mutually-parallel partially-reflecting surfaces (17) located between, and oriented non-parallel to, a pair of major external surfaces, and at least one region (30a, 30b, 30c) without partially-reflecting surfaces. The method includes bonding together parallel-faced plates (4) at interfaces to form a stack (42) of plates with partially-reflecting coatings between them. The stack is cut and polished to form a boundary plane (48, 48a, 48b) intersecting the interfaces, and a block (50, 50a, 50b) of transparent material is bonded to the stack. The resulting precursor structure (52, 52′) is sliced along parallel planes to form slices, each containing a part of the stack for the active region of the LOE and a part of the block.

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.
