LASER CENTRALIZER OF X-RAY RADIATOR Russian patent published in 2003 - IPC

FIELD: X-ray equipment. SUBSTANCE: laser centralizer has case housing X-ray radiator, mirror, TV camera, personal computer, illuminator and three microlasers. Two microlasers are positioned in front of lens of TV camera, fitted with cylindrical lenses to form flat beams parallel one another and forming two parallel stripes. Distance between stripes determines size of base of range-finding system comprising TV camera and computation systems based on personal computer. Third microlaser is employed in the capacity of laser indicator of crossing point of axis of X-ray beam with object which radiation is directed on object with the aid of mirror and two micromirrors. One micromirror is installed in front of lens of TV camera, second micromirror is placed in front of front lens of illuminator comprising lenses arranged in symmetry. Separable light filters are located between lenses. Diaphragm is mounted in front of first lens. EFFECT: increased accuracy of determination of focal distances thanks to objectivity of measurement of size of image of laser spot on object including interactive mode, provision for observation of section of object present in beam of X-ray radiator and possibility of its observation in white light. 1 dwg
