  • Patent number: 10386614
    Abstract: An optical apparatus includes plural optical lens groups with a specified field of view and an optical sensor accommodated and fixed within a casing. After a light beam passes through any of the plural optical lens groups, its travelling direction is changed, and it is sensed by the optical sensor and converted into an image signal by the optical sensor. The optical apparatus has a single optical lens module of minimized volume and is able to implement different optical functions simultaneously. Consequently, the fabricating cost of the optical apparatus is reduced, the assembling process is simplified, and the number of components to be assembled is reduced.

  • Patent number: 8861907
    Abstract: In one embodiment, an apparatus may include an optical fiber that may have a surface non-normal to a longitudinal axis of a distal end portion of the optical fiber. The surface may define a portion of an interface configured to redirect electromagnetic radiation propagated from within the optical fiber and incident on the interface to a direction offset from the longitudinal axis. The apparatus may also include a doped silica cap that may be fused to the optical fiber such that the surface of the optical fiber may be disposed within a cavity defined by the doped silica cap.

  • Patent number: 8818149
    Abstract: Exemplary apparatus for obtaining information for a structure can be provided. For example, the exemplary apparatus can include at least one first optical fiber arrangement which is configured to transceive at least one first electro-magnetic radiation, and can include at least one fiber. The exemplary apparatus can also include at least one second focusing arrangement in optical communication with the optical fiber arrangement. The second arrangement can include a ball lens, and be configured to focus and provide there through the first electro-magnetic radiation to generate the focused electro-magnetic radiation. Further, the exemplary apparatus can include at least at least one dispersive third arrangement which can receive a particular radiation (e.g., the first electro-magnetic radiation(s) and/or the focused electro-magnetic radiation), and forward a dispersed radiation thereof to at least one section of the structure.

  • Publication number: 20140147087
    Abstract: A contoured display that includes a faceplate configured to propagate an image in a collimated manner from an interface surface of the faceplate configured to receive the image from a display device to a display surface of the faceplate. The display surface is contoured to provide a three-dimensional (3D) contoured surface that provides designers with artistic freedom when designing a display shape, and a convenient way to contour a display surface to reduce the effects of glare on the display surface.

  • Patent number: 8668640
    Abstract: Endoscopes and other viewing devices that control the light that contacts a sample and/or that is detected emanating from a sample. The viewing devices are particularly well suited for in vivo imaging, although other uses are also included. The viewing devices, and methods related thereto, comprise a spatial light modulator in the illumination and/or detection light path so that light transmitted to the target via a bundle of light guides or optical system is transmitted substantially only into the cores of the light guide bundle and not into the cladding surrounding the light guides, filler between the light guides in the bundle, or undesired light guides. Also, methods and apparatus for mapping the pixels of the spatial light modulator to the cores of the light guides in the bundle (preferably at least 3 pixels (e.g., at least 3 mirrors for a digital micromirror device) for each core), as well as for mapping the light guides of one light guide bundle to another.

  • Patent number: 8666212
    Abstract: An optical apparatus of a head mounted display includes a fused fiber bundle, an image source, and an image lens. The fused fiber bundle includes an array of fused optical fibers having an in-coupling surface located at a first end and an out-coupling surface physically facing an eye-ward direction and located at a second end. The fused fiber bundle is tapered such that the in-coupling surface has a larger surface area than the out-coupling surface to compress the light image. The image source is disposed at the first end of the fused fiber bundle and optically aligned with the in-coupling surface to launch the light image into the fused fiber bundle. The image lens is disposed at the second end and optically aligned with the out-coupling surface to focus the light image emitted from the second end towards an eye when the head mounted display is worn.
