Claims

A laser centralizer for an x-ray emitter, comprising a housing with a laser located therein, whose optical axis is parallel to the longitudinal axis of the x-ray emitter, two mirrors, the first of which is made of plexiglass, are installed at the intersection of the optical axes of the laser and x-ray radiation beams, perpendicular to the plane they form in the guide a collimated laser beam concentric with an X-ray beam, a scale, a telescope for expanding and collimating laser radiation, consisting of an infrared lens and a lens, which allows using the first mirror, the lens and the second mirror, made translucent, to form in the focal plane of the telescope lens, coinciding with the scale, a real image of the luminous disk obtained on the surface of the object in the area of illumination by a laser beam, a television system including a television camera and video control the device, the scale being linear, mounted in front of the laser and located in the focal plane of the telescope objective in such a way that The scale and the area of the object illuminated by the laser beam are projected by an additional micro lens into the plane of the miniature CCD matrix of the camera, the video signal from which is fed to the input of the video monitoring device, on the screen of which the image of the laser spot is observed and its size is estimated using the image of a linear scale, the divisions of which are digitized directly in the focal lengths of the x-ray emitter and the number of which passing on the image of the laser spot determines the focal length of the x-ray novskogo emitter for its specific position relative to the object, characterized in that it contains a fiber and a light source, the output end of the fiber having dimensions and shape identical to the size and shape of the focal spot of the x-ray emitter, and is mounted on the optical axis of the laser emitter coaxially with it between the first mirror and telescope lens at a distance

from the point of intersection of the optical axis of the laser emitter with the first mirror equal to the distance A 'from the focal spot of the x-ray emitter to the point of intersection of the axis of the x-ray beam with the first mirror, in front of the output end of the fiber on its optical axis at a distance

a diaphragm with a radius hole is installed from it

, the value of which is related to the distance K by the ratio R = K • tgβ, where β is the half-width of the opening angle of the x-ray beam, the illuminator is installed in front of the input end of the fiber on its optical axis coaxially with it, contains a light source, optical filters and a modulator for adjusting brightness, color and modulation of the beam of optical radiation entering the fiber and the capacitor for focusing on the input end of the fiber optic beam with an aperture angle

whose value is associated with the aperture angle of the fiber

and the half-width of the opening angle of the x-ray beam with the relation α ≥ u ≥ β.
