    摘要： In order to sort diamond-bearing ore particles conveyed on a wide belt, exciting radiation strikes the belt along an extended line. Diamonds are detected by passing the emitted radiation through a narrow band pass filter and sensing the Raman radiation with a photo-multiplier tube. Only axial-parallel rays passing through the filter reach the photo-multiplier tube. An array of side-by-side converging lenses can be used, the lenses being of rectangular shape as seen looking along the optical axis with their long axes at right angles to the line of radiation. The ore particles are in the plane of the foci of the lenses, so that radiation emitted by each particle is passed in parallel rays through the filter. In order to stop rays having an angle of incidence greater than the maximum permitted, to avoid identifying non-diamond material as diamond, a further converging lens is used to focus the rays at the plane of a telecentric stop. The stop stops rays having too great an angle of incidence. The position of the diamond can be detected for instance by a CCD array or by a time domain technique. The apparatus can be monitored by giving a signal when the radiation from tracer stones and holes on either side of the belt, differs from predetermined values.

    摘要： The invention relates to an infrared ray moisture meter which measures moisture of paper using absorption of infrared rays, and in which infrared rays being penetrated and scattered by the paper are sufficiently independent of whether the paper is thin or thick, in which sensitivity is high, in which attenuation of rays is small and error due to misalignment in the XY direction is small. Also, concurrently, in the invention, adverse influence due to quality of the paper is reduced by applying infrared rays which are absorbed by moisture, infrared rays which are absorbed by cellulose, and infrared rays which are not absorbed by moisture or cellulose, and by computing the value of moisture from signals detected from the application of the different infrared rays. In one embodiment a device is provided with a shielding plate having two mirrored surfaces disposed between the paper being measured and a lower one of a pair of reflectors.

    摘要： [Object] To perform shape inspection of a metallic body in a simple way at higher speed with higher density.[Solution] An apparatus of the present invention includes: a measurement apparatus configured to irradiate a metallic body with at least two illumination light beams, and measure reflected light separately; and an arithmetic processing apparatus configured to calculate information used for shape inspection of the metallic body on the basis of measurement results. The measurement apparatus includes a plurality of illumination light sources configured to emit strip-shaped illumination light having different peak wavelengths, and a plurality of monochrome line sensor cameras that have band-pass filters and are aligned vertically above a surface of the metallic body and set to capture images of the same portion of the metallic body by their respective shift lenses, the number of the monochrome line sensor cameras being the same as the number of the peak wavelengths of the emitted illumination light. At least two of the plurality of illumination light sources are provided in a manner that an angle formed by a normal direction to the surface of the metallic body and an optical axis of the first illumination light source is substantially equal to an angle formed by the normal direction and an optical axis of the second illumination light source and the two illumination light sources face each other with the line sensor cameras therebetween in a relative movement direction of the metallic body and the measurement apparatus.
