  • Patent number: 10580307
    Abstract: An AIS information display device comprises an information acquisition component, an icon generator, and a display component. The information acquisition component acquires bearing information, which is information about the bearing of other targets with respect to the position of the host vessel. The icon generator uses an icon-use host vessel symbol S3 and one other target symbol S2 to generate an icon 19 that indicates the relative bearings of the host vessel and another target. The display component displays the icon 19 generated by the icon generator. Consequently, a ship display device can be provided which makes every target easy to understand, even when there are many other targets around the host vessel.

  • Patent number: 9071035
    Abstract: An optical amplifier comprising: a pumping light source supplying a pumping light to an optical fiber as an amplification medium; an ASE light power detector detecting an ASE light power including an external ASE power flowing from an upstream side outside an amplification signal band; and a control unit setting a gain within the amplification signal band by using the ASE light power detected by the ASE light power detector outside the amplification signal band. The control unit controls the pumping light source by compensating for an influence of the external ASE power, obtained by measuring a relationship between the gain within the amplification signal band and the ASE light power outside the amplification signal band, to set initially the gain within the amplification signal band.

  • Patent number: 8730465
    Abstract: A defect inspecting apparatus inspects defects of a sample having a pattern formed on the surface. The defect inspecting apparatus is provided with a stage which has a sample placed thereon and linearly moves and turns; a light source; an illuminating optical system, which selects a discretionary wavelength region from the light source and epi-illuminates the sample surface through a polarizer and an objective lens; a detecting optical system, which obtains a pupil image, by passing through reflection light applied by the illuminating optical system from the surface of the sample through the objective lens and an analyzer which satisfies the cross-nichols conditions with the polarizer; and a detecting section which detects defects of the sample by comparing the obtained pupil image with a previously stored pupil image. Conformity of the pattern on a substrate to be inspected can be judged in a short time.

  • Patent number: 8040512
    Abstract: An illuminating optical system of an inspection device selects an arbitrary wavelength region from the light source, and epi-illuminates the sample via the polarizer and the objective lens. A detecting optical system includes an analyzer having a polarization plane intersected with a polarization direction of the polarizer. Then, the detecting optical system detects light from the sample via the objective lens and the analyzer, and acquires a Fourier image of a sample surface based on this light. An imaging section images the Fourier image. An analyzing section performs computation for processing for determining a notable area to be affected by a state of the pattern more than other areas in the Fourier image.

  • Publication number: 20100245811
    Abstract: An inspecting apparatus (1) obtains a pixel from among pixels of a DMD element (31) for guiding light from a wafer (W) to detecting elements (36a, 36b, 36c), based on luminance information on Fourier image obtained by detection by a two-dimensional imaging element (33) when the inspecting apparatus is set to guide all the light from the wafer (W) to the two-dimensional imaging element (33) by having all the pixels (micro mirrors) of the DMD element (31) in the on-state. Then, the inspecting device brings the obtained pixel of the DMD element (31) into the off-state, reflects a part of the light from the wafer (W) by the pixel in the off-state and guides the light to the detecting elements (36a, 36b, 36c).
