LASER POSITIONER FOR X-RAY EMITTER Russian patent published in 2009 - IPC H05G1/00 

FIELD: physics.

SUBSTANCE: invention can be used for aligning an X-ray emitter with respect to an object. The laser positioner has a housing in which there is a laser, the optical axis of which is parallel to the longitudinal axis of the X-ray emitter, two mirrors, the first of which is made from organic glass and mounted at the intersection of optical axes of the laser and X-ray beams, directing laser beams onto the object, concentric with the axis of the X-ray beam, the second mirror, which is semi-transparent and mounted on the axis of the laser between the laser and the first mirror, a television system, consisting of a CCD matrix and a monitor, the axis of the lens of the CCD matrix passes through the point of intersection of the second mirror and the axis of the laser perpendicular the mirror and a ring-shaped laser matrix, mounted symmetrically about the axis of the laser perpendicular to it between the laser and the second mirror, a narrow band light filter, the bandpass of which coincides with the wavelength of the laser radiation, mounted in front of the lens of the television system. A laser range-finder, mounted inside the housing of the positioner, is used for measuring the distance from the object to the X-ray emitter. The beam of the laser range-finder propagates with the help of the first mirror in the direction which coincides with the axis of the X-ray beam. There is also a base, on which the housing of the positioner is mounted, with possibility of rotating about an axis which coincides with the axis of the laser range-finder. A self-aligning laser level with a flat a flat divergent beam is fixed on the base. On the axis of rotation of the housing, there is a goniometric scale with an index, fixed to the base, a locking device for holding the housing in the required angular position.

EFFECT: more accurate alignment of the axis of the X-ray beam about the surface of an object.
