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 first mirror, mounted at an angle of 45° to the axis of the X-ray beam at the point of intersection of the axis of the X-ray beam and an axis, parallel to the longitudinal axis of the X-ray emitter and passing at a certain distance from the focus of the X-ray tube, a laser range-finder and a television system, consisting of a television camera based on a CCD matrix, a lens and a monitor, situated outside the exposure zone of the X-ray beam. In front of the lens of the television camera, there is a narrow-bandpass filter, bandpass of which coincides with the wavelength of the laser, used in the positioner for illuminating the object. The axis of the laser is parallel to the longitudinal axis of the X-ray emitter and passes through the centre of the first mirror, a rotor with a central axial opening, lying on the axis of the laser between the laser and the first mirror. A semi-transparent mirror and a second mirror are mounted in series on the surface of the rotor, perpendicular the axis of the laser and facing the first mirror, along one of its radii.

EFFECT: higher degree of visualisation of zones on an object exposed to X-rays, as well as easier adjustment of ring-shaped laser matrix.
