stereo photography device

Abstract

Abstract PURPOSE:To permit stereoscopic photographing which can measure X-ray images at a high speed by bisecting synchrotron radiation light and macro-reflecting said light to form two sets of beams each having a rectangular section and projection the same on a specimen from different directions. CONSTITUTION:A single crystal 2 is so cut out that the surface thereof is parallel with the diffraction crystal plane. Only the X-ray of the energy E=12.4/(2d sintheta) (unit of E is keV, d is spacing between crystal lattice planes and the unit thereof is Angstrom) is reflected by the principle of Bragg reflection with respect to the incident X-rays at an angle with the diffraction crystal plane. The beam is bisected and the direction of the monochromatic beam of the energy E entering the single crystal 3 is varied by -2 - or + by the diffraction effect and is emitted in the end in the same direction as the direction of the original beam. The component of the energy E of the incident beam on the single crystal 4 is rotated by 2theta with respect to the incident beam. A specimen 5 is placed in the position where the two rectangular beams intersect with each other at the angle 2theta and the monochromatic X-rays transmitted through the specimen are measured by two sets of X-ray image detectors 6 and 7, by which the stereoscopic photographing is realized.
