  • Patent number: 8975564
    Abstract: This invention advances the related state-of-the-art by eliminating the physical EO window used by electro-optical imaging infrared seekers for tactical missiles and high-altitude endo-atmospheric interceptors, widely employed in integrated defense systems. This invention increases the probability of intercepting exo-atmospheric ballistic warheads by exo-atmospheric interceptors, and eliminates the existing altitude “gap” of interception, as well as the geographical limitations posed by the mesospheric Noctilucent Clouds. The problem of protecting an imaging EO sensor from aeroheating is solved in this invention by a special purpose device which is enabled immediately after the nose cone ejection event.

    Abstract: A method to prepare low reflective surface according to an example of the present invention comprises: the first step to prepare materials having pillar structure on the surface; the second step to prepare aluminum surface-materials by treating for the pillar structure to have aluminum surface; and the third step to prepare a low reflective surface with dual protuberance structure by forming nano-flake layer on the pillar surface of the material surface through oxidation of the surface aluminum of the aluminum surface-materials. The method to prepare low reflective surface can provide a low reflective surface structure that can be applied to photovoltaic device surface or various display surface as a surface able to reduce reflection significantly by absorbing wavelengths in the range of visible and infrared ray through internally total reflection with simple, low cost, and ecofriendly process.

  • Publication number: 20140313452
    Abstract: Exemplary embodiments disclosed herein provide a glass assembly having a bottom sheet of glass which is substantially planar, bonded to a top sheet of glass which is substantially concave. A layer of adhesive is preferably interposed between the bottom and top sheets of glass. In an exemplary embodiment, the amount of adhesive used would be less than the amount required to hold both sheets of glass in a parallel planar arrangement. The layer of adhesive may be contained between the two sheets of glass by a perimeter of adhesive tape, also interposed between the top and bottom sheets of glass. The assembly can be used with an electronic display where the display is positioned adjacent to the top sheet of glass, and due to its concavity, the electronic display can bow towards the top sheet of glass without actually contacting the glass.

  • Patent number: 8840258
    Abstract: The present invention provides such a formation method that an antireflection structure having excellent antireflection functions can be formed in a large area and at small cost. Further, the present invention also provides an antireflection structure formed by that method. In the formation method, a base layer and particles placed thereon are subjected to an etching process. The particles on the base layer serve as an etching mask in the process, and hence they are more durable against etching than the base layer. The etching rate ratio of the base layer to the particles is more than 1 but not more than 5. The etching process is stopped before the particles disappear. It is also possible to produce an antireflection structure by nanoimprinting method employing a stamper. The stamper is formed by use of a master plate produced according to the above formation method.

  • Patent number: 8840257
    Abstract: An antireflection film, including an optical element, formed on an optical surface of an optical member and preventing reflection of a light beam incident on the optical surface. It has a maximum reflectance P1 in a first wavelength region and a maximum reflectance P2 in a second wavelength region at a wavelength side longer than the first wavelength region, and satisfies a relation of P1>P2, as a spectral reflectance property when a light beam is incident on the optical surface at a 0 degree incident angle. It also shifts a wavelength range where the reflectance is a specific value or less, to a wavelength longer than the second wavelength region, the reflectance in the second wavelength region decreases, and the reflectance in the first wavelength region increases so that a luminance difference is small between a ghost in the first wavelength region and the second wavelength region.
