Claims (1)

A laser centralizer for an x-ray emitter, comprising a housing with a television system located in it, the optical axis of the lens of which is parallel to the longitudinal axis of the x-ray emitter, a plexiglass reflector mounted at the intersection of the axes of the camera lens and the x-ray beam perpendicular to the plane formed by these axes, and a video monitoring device that differs the fact that it additionally contains two microlasers, the optical axis of which are parallel to each other, and the x-ray axis of the beam are symmetrical about this axis in the plane formed by the axes of the lens of the television system and the x-ray beam at a distance B from each other, determined from the relation

where D _min - the minimum distance from the emitter to the object; α is the angular size of the x-ray beam in the working range of these distances, the focal length of the lens of the television system f 'is related to the size of the CCD matrix H of the television system by the ratio

To determine the distance from the emitter to the object, a television computer or computer is used that automatically calculates this distance using the formula  D = C / B, where C = B · f ’- the constant of the optical system of the centralizer; В ’- the distance between the images of laser spots on the object in the focal plane of the lens of the television system, which coincides with the plane of the photosensitive elements of the CCD matrix, at the same time, a digital camera was used to record, store and transmit images of the surface of the object in the area of its transmission through X-ray radiation to a computer.
