  • Patent number: 9013713
    Abstract: The present invention aims to provide a highly reliable relief pattern detection device 1, including a slant FOP 3 having an input end surface 4 with which an object surface makes contact and an output end surface 5 substantially parallel to the input end surface 4, an irradiation light source 10 disposed on the output end surface 5 side of the slant FOP 3, for irradiating the output end surface 5 with light, and a CCD camera 11 disposed on the output end surface 5 side of the slant FOP 3, for detecting a relief pattern based on light emitted from the output end surface 5, in which optical axes Rf of optical fibers are inclined so as to create a first angle ? less than 90° in one direction from the output end surface 5 within a predetermined plane substantially perpendicular to the output end surface 5, the irradiation light source 10 irradiates the output end surface 5 with light in a direction to create a second angle ? less than 90° in the other direction from the output end surface 5 within the predetermi

  • Patent number: 7705315
    Abstract: An Ag film as a light-reflecting film is formed on one surface of an a-C substrate of a scintillator panel. The entire surface of the Ag film is covered with an SiN film for protecting the Ag film. A scintillator having a columnar structure, which converts an incident radiation into visible light, is formed on the surface of the SiN film. The scintillator is covered with a polyparaxylylene film together with the substrate.
