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 housing in which there is a laser with a double-sided radiation output, three reflectors, the first of which is semi-transparent and mounted at the intersection of the optical axis of the laser with the axis of the X-ray beam, the second is mounted on the optical axis of the radiation output of the laser beyond the projection of the output window of the X-ray emitter on it, with possibility of its rotation about an axis perpendicular the plane, given by the optical axis of the radiation output of the laser and the axis of the X-ray beam, the third reflector is similar to the second and is mounted symmetrical with the second about the axis of the X-ray beam, apparatus for indicating distance from the X-ray emitter to the object, two cylindrical lenses, mounted on the axis of the laser across each of its output beams with possibility of rotation about the axis of the laser, the first of which is situated between the second reflector and the second butt end of the laser emitter, and the second - between the third and first reflectors, the second and third reflectors are mounted with possibility of synchronous and opposite rotation, two shutters for shuttering laser beams from the second and third reflectors, and additionally, a beam splitting prism block, lying on the axis of the laser between the third reflector and the second cylindrical lens, the block consists of a beam splitter prism-cube and a rectangular prism, reflecting surfaces of which are parallel each other and are perpendicular to the plane, formed by axes of the laser and X-ray beams.

EFFECT: increased accuracy of determining alignment of two identical laser strips, as well as shorter time on measuring distance to an object.
