  • Publication number: 20150237326
    Abstract: A 3D image apparatus using a single optical channel for capturing multiple view-angle images of an object for use in generating a 3D image or model of the object. The apparatus includes within the optical train an active optical component, an aperture plate having an aperture, a lens for focusing light from the aperture, and an image sensor. The active optical component has a changeable shape or position for providing first and second optical wavefronts through the aperture and focused by the lens onto the image sensor from first and second view angles of the object. The second optical wavefront is shifted by the active optical component on the image sensor with respect to the first optical wavefront in order to provide multiple view-angle images along the single optical channel, which can be used to generate a 3D model or image of the object.

  • Patent number: 9110245
    Abstract: Multilayer reflecting polarizing films are disclosed having increased in-plane refractive index differences between adjacent microlayers along both the pass and block axis, and having negative refractive index differences between adjacent microlayers along the thickness or z-axis. Major front and back surfaces of the film exposed to air provide a Fresnel reflectivity component to the pass axis reflectivity, and the microlayers provide a microlayer component to the pass axis reflectivity, such microlayer component preferably having a reflectivity of p-polarized light that increases with incidence angle faster than the Fresnel reflectivity component decreases so as to substantially avoid off-axis gain peaks for p-polarized light. The films preferably utilize a relatively small total number of microlayers, arranged in a single coherent stack with monotonic optical repeat unit thickness profile, and at least some microlayers preferably include polyethylene naphthalate or a copolymer thereof.

  • Publication number: 20150228868
    Abstract: Broadband solid state light sources include remote phosphor LED(s), short-wavelength direct emitting LED(s), and long-wavelength direct emitting LED(s). A diffuse or clear cover member covers these LEDs. Each remote phosphor LED includes an LED, a phosphor layer, and a dichroic reflector. The light sources can provide a broadband output light over a wide color range, and can do so efficiently while energizing a high percentage or proportion of the total number of LEDs in the system. The broadband output may for example exhibit a color difference of at least 0.2 in CIE chromaticity units, and/or a correlated color temperature difference of at least 4000 or 5000 Kelvin, while energizing more than half, or at least 60%, or at least 70%, of the total number of LEDs. Numbers of LEDs can be replaced with effective numbers of LEDs if LEDs of substantially different sizes are included in the light source.
