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: A first dichroic beamsplitter is deployed in a first prism on a plane oblique to a light-wave entrance surface. A second dichroic beamsplitter is deployed in a second prism on a plane oblique to a light-wave entrance surface such that polarized light in a first polarization state relative to the first dichroic beamsplitter is in a second polarization state relative to the second dichroic beamsplitter. The first dichroic beamsplitter transmits polarized light of a first color in the first polarization state relative to the first dichroic beamsplitter, and reflects polarized light of a second color in the first polarization state relative to the first dichroic beamsplitter. The second dichroic beamsplitter transmits polarized light of the first and second colors in a second polarization state relative to the second dichroic beamsplitter, and reflects polarized light of a third color in the first polarization state relative to the second dichroic beamsplitter.

Abstract: 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.

Abstract: A light-transmitting substrate has parallel surfaces deployed with a first of the parallel surfaces in facing relation to an eye. An optical element is associated with the first surface and applies optical power to incident light of a first type so as to collimate the incident light, and applies substantially no optical power to incident light of a second type. An optical coupling configuration is associated with the substrate and is configured for coupling-in a proportion of collimated light of the first type incident on the first surface so as to propagate within the substrate, and for coupling-out a proportion of light of the second type propagating within the substrate. Optics associated with the substrate convert collimated light of the first type into converging beams of light, which are sensed by an optical sensor. A processor derives current gaze direction of the eye by processing signals from the optical sensor.

Abstract: An image projector with a high optical efficiency projects an image at an arbitrary distance from an observer. The image projector includes an illumination module having at least one spatially coherent light source; a phase image generator with an array of optical phase shifting elements; an electronic image controller connected electrically to the phase image generator; and a waveguide which includes at least one embedded partial reflector. The waveguide may be positioned either between the illumination module and the waveguide, or between the waveguide and the observer. The phase image generator may include phase shifts for canceling speckle, correcting optical aberrations, and/or compensating interference caused by light rays having different optical path lengths.

Abstract: A light-transmitting substrate is deployed with a first of two major surfaces in facing relation to an eye of a viewer and guides light by internal reflection between the two major surfaces. An optical coupling-out configuration couples image light, that corresponds to a collimated image and that is guided by internal reflection between the two major surfaces, out of the light-transmitting substrate. A first optical coupling configuration collimates light from the eye to produce collimated light, and couples the collimated light into the light-transmitting substrate for guiding by internal reflection. A second optical coupling configuration couples the collimated light out of the light-transmitting substrate toward an optical sensor that senses the coupled-out light. A processing system derives current gaze direction of the eye by processing signals from the optical sensor.

Abstract: Disclosed herein is an optical assembly for generating a color image using white light as source. The optical assembly includes a broadband white light source array, a color filter assembly configured to allow selectively filtering therethrough light in each of three additive primary colors, and a control unit. The control unit is configured to actuate light sources in the light source array according to three intensity maps. Each of the intensity maps corresponds to one of the three additive primary colors. The control unit is further configured to synchronize operations of the light source array and the color filter arrangement such that, when light sources in the light source array are actuated according to one of the three intensity maps, the color filter arrangement filters therethrough light at the additive primary color to which the intensity map corresponds.

Abstract: A vehicular head-up display (HUD) for displaying an image to a user of a vehicle having a windshield (15) includes an image projector (14) outputting a collimated image and an optical aperture expander. The optical aperture expander includes a light-guide optical element (LOE) (10) having two major external surfaces (30a, 30b). The image projector (14) injects the collimated image so as to propagate within the LOE by internal reflection at the major external surfaces. The LOE also has a set of parallel partially-reflecting internal surfaces (12) which progressively couple out the image illumination from the LOE. The optical aperture expander is deployed such that the image illumination coupled-out of the LOE (12) follows a light path including a reflection from a surface associated with the windshield (15) of the vehicle so as to be visible to the user while the user looks at a scene beyond the windshield.

Abstract: 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.
