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 for an X-ray emitter has a housing in which there is a laser, a first mirror made from organic glass, mounted at the intersection of the optical axes of the laser and X-ray beams, which directs onto the object a laser beam, concentric with the X-ray beam, a television system, consisting of a CCD matrix, a lens and a monitor, a linear scale, digitised in distances from the object to the X-ray emitter, which is projected on the CCD matrix using the first semi-transparent mirror and the lens and which is viewed on the screen of the monitor simultaneously with the image of the controlled zone of the object and ring structures formed by the laser beam. The positioner also contains a rotor with an central opening, lying on the axis of the laser between the laser and the first mirror with possibility of rotation, on the surface of the rotor, facing the perpendicular axis of the laser and the first mirror, along one of its radii there is a second mirror, mounted at an angle of 45° to the axis of the laser at a distance R from the laser and in series with a second semi-transparent mirror, mounted at an angle to the axis of the laser at a distance H from the laser, where α - is the angle of divergence of the X-ray beam and a third semitransparent mirror, mounted in front of the central opening of the rotor directly on the axis of the laser at an angle of 45°, the plane of the second mirror and third semi-transparent mirror are parallel to each other.

EFFECT: increased intensity of laser radiation, provision for illumination of the centre of the zone illuminated by the laser, simpler design.
