LASER CENTRALIZER FOR X-RADIATOR Russian patent published in 1998 - IPC

FIELD: checking of materials by radiation method. SUBSTANCE: device has body which accommodates laser with two-way output of radiation. Optical axis of radiation output is parallel to longitudinal axis of X-radiator. Device also has two reflectors. First reflector is made of organic glass and positioned at point of intersection of laser optical axis with radiator X-ray. Second reflector is mounted for turning about axis in parallel to axis of turn of first reflector, on radiation output axis, beyond projection of X-radiation output window on it. In addition, device has focal distance indicator and interrupter of second reflector beam positioned upstream or downstream the second reflector. Centralizer is provided with two cylindrical lenses installed on laser radiation axis. First lens is placed between one of faces of laser radiator and first reflector, and second lens is installed between second face of laser radiator and second reflector. Their focus is selected from relation f=h/tga, where h is laser beam radius, and a is X-beam radiation angle. Cylindrical lenses are mounted for rotation around laser beam axis. EFFECT: more effective checking. 3 dwg
