Patent number: 11933985Abstract: 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.Type: GrantFiled: February 2, 2021Date of Patent: March 19, 2024Assignee: LUMUS LTD.Inventors: Ido Fuchs, Edgar Friedmann, Elad Sharlin, Kobi Greenstein, Lilach Zuaretz, Tsion Eisenffeld, Shimon Grabarnik, Amir Shapira, Dror Hermoni

Patent number: 11662311Abstract: 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.Type: GrantFiled: December 7, 2021Date of Patent: May 30, 2023Assignee: LUMUS LTD.Inventors: Chaim Aldaag, Tzofia Lavi, Dror Hermoni, Jonathan Gelberg, Yosef Lavian, Netanel Goldstein, Elad Sharlin, Elad Lavi, Kobi Greenstein, Amir Shapira, Mordechai Gilo, Tsion Eisenfeld

Publication number: 20230037873Abstract: Optical sample characterization facilitates measurement and testing at any angle in a full range of angles of light propagation through an optical sample, such as 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 with a known refractive index. An optical light beam is input normal to the surface of the cylinder, travels through the cylinder, then via the fluid, to the optical sample, where light beam is transmitted and/or reflected, then exits the cylinder and is collected for analysis. Due at least in part to the fluid surrounding the optical sample, the optical sample can be rotated through a full range of angles (±90°, etc.) for full range testing of the optical sample.Type: ApplicationFiled: April 25, 2021Publication date: February 9, 2023Inventors: Eitan RONEN, Eitan BAIBICH, Elad SHARLIN, Amir SHAPIRA, Jonathan GELBERG, Netanel GOLDSTEIN, Elad LAVI

Publication number: 20210271006Abstract: A near-eye display includes a light-guide optical element (LOE) (10) having first and second major external surfaces (11A, 11B) that are planar and mutually parallel. An image projector (2) introduces into the LOE illumination corresponding to an image so that the illumination propagates within said LOE by internal reflection at the major external surfaces. A coupling-out arrangement couples the illumination out of the LOE towards the eye of the observer. The coupling-out arrangement may be a set of mutually-parallel, partially-reflective surfaces (12A) deployed at an oblique angle within the LOE. Various arrangements for suppressing reflections of ambient light sources include obstructing baffles oriented so as to avoid reduction of peripheral field of view, various non-reflective coatings and various deployments of polarization filters.Type: ApplicationFiled: August 26, 2019Publication date: September 2, 2021Inventors: Eitan RONEN, Yochay DANZIGER, Jonathan GELBERG, Tsion EISENFELD, Amir SHAPIRA
