Abstract:
A near-to-eye display device includes a spatial light modulator and a microdisplay. The spatial light modulator provides a high-resolution focused image for central vision. The microdisplay provides a low-resolution defocused image for peripheral vision. The display has a large field of view.
Abstract:
Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer film to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lens around the photopolymer film; sandwiching photopolymer film in between two portions of a lens; applying photopolymer film to a concave surface of a lens; and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.
Abstract:
A system for generating and displaying holographic visual aids associated with a story to an end user of a head-mounted display device while the end user is reading the story or perceiving the story being read aloud is described. The story may be embodied within a reading object (e.g., a book) in which words of the story may be displayed to the end user. The holographic visual aids may include a predefined character animation that is synchronized to a portion of the story corresponding with the character being animated. A reading pace of a portion of the story may be used to control the playback speed of the predefined character animation in real-time such that the character is perceived to be lip-syncing the story being read aloud. In some cases, an existing book without predetermined AR tags may be augmented with holographic visual aids.
Abstract:
A mobile terminal according to one embodiment of the present invention comprises: a first body and a second body detachably attached to each other; a first light source on the first body so as to provide light to the second body; a first filming unit, on the second body, for forming a first hologram by means of light supplied from the first light source. Thus more diverse holographic images can be produced by replacing the first body.

Abstract:
An ophthalmic device which comprises a holographic element comprising a medium comprising a phenylboronic acid group and, disposed therein, a hologram, wherein an optical characteristic of the element changes as a result of a variation of a physical property of the medium, and wherein the variation arises as a result of interaction between the medium and an analyte present in an ocular fluid.
Abstract:
A total reflection surface and a holographic optical element (HOE) surface are formed on the same surface (S3) in an eyepiece prism (15). In this structure, a smaller reflection angle can be set at an HOE (16) compared to a structure with the surface formed separately, and the HOE surface of the surface (S3) can be set in the direction parallel to a surface (S2). Thus, even in a structure in which at least a portion of the light flux of the image light fully reflected by the surface (S3) is incident on an affixing region (R1) of a hologram photosensitive material (16a), that portion of the light can be prevented from falling incident on the optical pupil (E) as ghost light. Consequently, in order to prevent the generation of ghost light, an optical path margin no longer needs to be provided between the diffraction and reflection region of the HOE (16) and the total reflection region of the image light; and the eyepiece prism (15) can be thinned by that amount. In addition, since a smaller reflection angle can be set at the HOE (16), the color dispersion caused by diffraction by the HOE (16) can also be reduced, and the image quality can be maintained.
Abstract:
The inventive method consists in transferring a pattern (P) onto the optical article (1) in the form of one or several portions of transferable material (3) retained by a pressure-sensitive adhesive material layer (2) and in applying transferable material portions with the aid of a pad by placing the adhesive material layer between the pad and a pattern receiving article. The use of the pressure-sensitive adhesive material makes it possible to use the different materials in the form of a transferable material. Said method is particularly suitable for producing patterns, in particular in the form of holograms on optical lenses, in particular ophthalmic lenses.
Abstract:
A holographic sensor comprising a thin film polymer matrix that undergoes a change in response to a substance to be sensed, the matrix containing within its volume a set of two or more holographic recordings, each recording providing a holographic image when the sensor is illuminated, wherein the presence or appearance of each image is visible to the eye as a function of the response of the sensor to the substance to be sensed. The images provide the dynamic range of the sensor. Such a sensor can be used to provide a visible image that changes or appears to the eye in response to an analyte.
Abstract:
The invention relates to a holographic viewing device that enables a given pattern to be properly viewed in place of light sources in a scene and is easy to fabricate and assemble with consistent characteristics, and a computer-generated hologram for the same. The invention provides a holographic viewing device in which computer-generated holograms 2 and 3 each constructed as a transmission Fourier transform hologram is fitted in a frame member 1. At least one of phase information and amplitude information recorded in a certain predetermined peripheral site of the computer-generated hologram 2, 3 relative to an input pattern reconstructible from the computer-generated hologram is removed.
