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 with a double-sided radiation output, a first reflector made from organic glass, mounted at the intersection of the axes of the laser and the X-ray beam, apparatus for indicating distance from the object to the X-ray emitter, a second reflector, mounted on the axis of the laser behind its second emitting end perpendicular the plane, formed by axes of the laser and X-ray beam at a constant angle to the axis of the laser with possibility of linear displacement along that axis. The first reflector is semi-transparent. There is also a third semi-transparent reflector made from organic glass, which is mounted on the axis of the X-ray beam between the X-ray emitter and the first reflector perpendicular the plane, formed by axes of the laser and X-ray beams, a television system, consisting of a monitor and television camera, comprising a lens and a CCD matrix. The television camera is placed in front of the third reflector. The optical axis of the lens of the television camera is parallel to the axis of the laser and passes through the point of intersection of the third reflector with the axis of the X-ray beam. There is a fourth reflector, the plane of which is parallel to the plane of the third reflector, and is mounted on the axis of the lens television camera at a certain distance from the point of intersection of the third reflector with the axis of the X-ray beam. There is a collimating lens, the axis of which passes through the centre of the fourth reflector, parallel the axis of the X-ray beam and perpendicular the plane of the digital display of the apparatus for indicating distance from the object to the X-ray emitter.

EFFECT: higher degree of visualisation of zones on an object exposed to X-rays, as well as increased accuracy of determining distance from the object to the X-ray emitter.
