LASER CENTRALIZER FOR X-RAY RADIATOR Russian patent published in 2005 - IPC

FIELD: nondestructive tests of equipment using roentgen rays.

SUBSTANCE: proposed device has two-way emitting laser, two reflectors of which one is installed at intersection point of optical axes of laser and X-ray beams and other one, past laser output window, as well as distance display means. This device is characterized in that it has circular illuminator mounted in plane crossing point of intersection of laser and X-ray beam axes perpendicular to the latter. Television system camera is disposed in location plane of circular illuminator; two additional reflectors having nonselective spectral characteristic are installed in front of television camera, one of them being semitransparent; reflecting faces of these reflectors are relatively parallel and are tilted through 45 deg. to camera axis; narrow-band optical filters are disposed in front of reflectors; their spectral characteristics are not intercepting and are chosen to ensure passage of either laser centralizer or circular illuminator light-emitting diode beams.

EFFECT: enlarged measurement range, enhanced contrast of laser bars.
