  • Patent number: 7948675
    Abstract: Multilayer-film reflective mirrors are disclosed that exhibit desired optical characteristics and resistance to reflective-surface degradation. An exemplary multilayer-film mirror includes a base and a multilayer film on the base. The multilayer film is made of first and second layers alternatingly laminated at a prescribed period length. The surface of the multilayer film has an irregular surface profile, relative to the surface profile of the base. The multilayer film reflects incident extreme ultraviolet (EUV) light. A third layer, situated on and covering the surface of the multilayer film, is formed of a substance having substantially the same refractive index to EUV light as the refractive index of a vacuum. The third layer has a surface profile substantially the same as the surface contour of the base. The third layer is covered with a protective layer.

  • Patent number: 7944609
    Abstract: A 3-D optical microscope, a method of turning a conventional optical microscope into a 3-D optical microscope, and a method of creating a 3-D image on an optical microscope are described. The 3-D optical microscope includes a processor, at least one objective lens, an optical sensor capable of acquiring an image of a sample, a mechanism for adjusting focus position of the sample relative to the objective lens, and a mechanism for illuminating the sample and for projecting a pattern onto and removing the pattern from the focal plane of the objective lens. The 3-D image creation method includes taking two sets of images, one with and another without the presence of the projected pattern, and using a software algorithm to analyze the two image sets to generating a 3-D image of the sample. The 3-D image creation method enables reliable and accurate 3-D imaging on almost any sample regardless of its image contrast.

  • Patent number: 7940456
    Abstract: An object of the present invention is to provide a three-dimensional image recording medium in which three-dimensional information of a recorded material is recorded precisely and observed more naturally. The linear images of plural parallel-projection images from different directions A to E divided into rectangles are recorded sequentially to divisional recording units of the linear image recording units M1 to M8 and in addition, the linear images of divided parallel-projection images from the same direction are recorded sequentially to each divisional recording unit arranged in the same position relative to a lens width direction of each lenticular lens unit L1 to L8 corresponding to each linear image recording unit M1 to M8 to thereby reproduce a three-dimensional image by combining the linear images of plural parallel-projection images.

  • Patent number: 7933069
    Abstract: A display device which is capable of generating more parallaxes without reducing resolution and an image quality, a display controlling method, and a program are provided. An aperture ratio of a light source is set as 1/N, and liquid lenses are disposed at distances of focal lengths of the first liquid lens and the second liquid lens from the light source, respectively. A position controlling portion changes a position of a nonpolar liquid by a size of each of luminescent pixels as represented by the first liquid lens and the second liquid lens, which results in that emitted lights from respective luminescent pixels pass through either the first liquid lens or the second liquid lens to be emitted in directions different from one another as shown in the form of lights. The present embodiments can be applied to a parallax image displaying device.

  • Patent number: 7894134
    Abstract: A linearly polarized transparent or translucent material is stretched to follow a sinusoidal shape so all parts of the resulting panes or lenses are themselves sinusoidal. By providing a structure of two panes or lenses of such material, moving one relative to the other in a linear direction varies an amount of light passing through. Thus, such a linear movement adjusts light translucence, luminosity intensity, brightness and dimness. Applications include windows (home, office, car), motor vehicle windshields, sunglasses, optical lenses, computer monitors, televisions, and fluorescent light fixtures.

  • Patent number: 7894131
    Abstract: A laser microscope is provided wherein a drop in output power in a positive-dispersion element used as a pulse compressor is reduced, thus improving multiphoton-excitation efficiency. Also, a size of the positive-dispersion element is reduced, thereby making it easier to attach the pulse compressor to a microscope main body and to accommodate the pulse compressor therein, thus improving maneuverability. The invention provides a laser microscope including a laser light source for emitting ultrashort-pulsed laser light; a pulse expander for expanding the ultrashort-pulsed laser light emitted from the laser light source; a large-diameter single-mode fiber for transmitting the ultrashort-pulsed laser light expanded by the pulse expander; a pulse compressor for compressing the ultrashort-pulsed laser light transmitted by the single-mode fiber; and a microscope main body for irradiating a specimen with the ultrashort-pulsed laser light compressed by the pulse compressor.
