Abstract: An eyepiece for a head mounted display (“HMD”) includes a doublet lens that includes a first optical element and a second optical element. The first optical element has an entry surface to receive the display light from a micro display and a first coupling surface. The second optical element has an exit surface and a second coupling surface paired to the first coupling surface of the first optical element. The doublet lens is configured to direct the display light through the first coupling surface, the second coupling surface, and through the exit surface.

Abstract: An optical element for a Head Mounted Display (“HMD”) includes a lightguide. The lightguide is embedded in the optical element and optically coupled to receive display light and direct the display light in an eyeward direction. The lightguide includes an eyeward hologram, a scene-side hologram, and a propagation region disposed between the eyeward hologram and the scene-side hologram. The eyeward hologram is configured to reflect a wavelength range of the display light that is incident upon the eyeward hologram at a specific angle. The scene-side hologram is configured to reflect the wavelength range of the display light that is incident upon the scene-side hologram at the specific angle.

Abstract: An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The light guide component includes an input surface to receive the display light into the light guide component, an eye-ward facing side, a world facing side, a total internal reflection (“TIR”) portion disposed proximal to the input surface to guide the display light received through the input surface using TIR, and a partially reflective portion including a partially reflective element disposed over the eye-ward facing side and a switchable reflector disposed over the world facing side. The partially reflective portion is disposed to receive the display light from the TIR portion and to guide the display light via reflections off of the partially reflective element and the switchable reflector.

Abstract: A lightguide assembly including structures to provide for outcoupling of light from an internal reflection structure. In an embodiment, a lightguide assembly includes light transmissive bodies forming respective corrugations which are coupled to one another. Optical coatings are variously disposed between the respective corrugations, wherein the optical coatings provide for redirection of light from the lightguide assembly. In another embodiment, optical coatings are each applied to a respective one of alternate facets of a corrugation. Polymer film portions provide mechanical support for the optical coatings during application to the corrugation.

Abstract: An eyepiece for a head mounted display (“HMD”) includes a doublet lens that includes a first optical element, a second optical element, and a reflecting element. The first optical element has an entry surface to receive the display light from a micro display and a first coupling surface disposed opposite the entry surface. The first optical element has a first index of refraction and a first Abbe number. The second optical element has an exit surface and a second coupling surface paired to the first coupling surface of the first optical element. The second optical element has approximately the first index of refraction and a second Abbe number different from the first Abbe number. The doublet lens and the reflecting element are configured to direct the display light through the entry surface, the first coupling surface, the second coupling surface, off the reflecting element, and through the exit surface.

Abstract: An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The light guide component includes an input surface oriented to receive the display light into the light guide component, an eye-ward facing surface having a reflection portion and a viewing portion, a folding surface oriented to reflect the display light received through the input surface to the reflection portion of the eye-ward facing surface, and a first interface surface oriented to receive the display light reflected from the reflection portion of the eye-ward facing surface. A partially reflective layer is disposed on the first interface surface in the viewing region to reflect the display light along the eye-ward direction through viewing portion of the eye-ward facing surface.

Abstract: Disclosed are imaging systems and eyeglass-based display devices. In one embodiment, an imaging system includes an image source that generates images, a optical element that manipulates the images, and a beam splitter positioned between the image source and the optical element that reflects the images onto an eye of a user of the imaging system, wherein each of the image source, optical element, and beam splitter are aligned along the same optical axis.

Abstract: An optical system, apparatus and method are capable of mutual occlusions. The core of the system is a spatial light modulator (SLM) which allows users to block or pass certain parts of a scene which is viewed through the head worn display. An objective lens images the scene onto the SLM and the modulated image is mapped back to the original scene via an eyepiece. The invention combines computer-generated imagery with the modulated version of the scene to form the final image a user would see. The invention is a breakthrough in display hardware from a mobility (i.e. compactness), resolution, and speed, and is specifically, related to virtual objects being able to occlude real objects and real objects being able to occlude virtual objects.

Abstract: In one embodiment, a system and method for designing an optical surface pertain to constructing a matrix of radial basis functions, each column of the matrix corresponding to a radial basis function, selecting an initial surface to be used as a starting point, selecting initial weights for the radial basis functions, generating an initialized optical surface based upon the selected initial surface and initial weights, and optimizing the initialized optical surface to minimize an error function.

Abstract: Short range communication systems and techniques are described. In an implementation an interrogator held near a person interrogates multiple transponders and receives information separately from the transponders. The interrogator and/or the transponders may be held in an article of clothing or in a personal effect of the person. The transponders may transmit identifying information and/or information associated with the states of the articles of clothing or personal effects of the person. Such a system enables the clothes worn by a person to communicate with a plurality of items and obtain useful information. In addition, a network system may be configured so that any particular transponder may communicate with another transponder or group of transponders of other locales to activate functions, cause actions or otherwise share data and/or information.
