SCANNING LASER X-RAY POSITIONER Russian patent published in 2006 - IPC H05G1/02 

FIELD: radiator positioning to object.

SUBSTANCE: newly introduced in proposed laser positioner are beam splitter disposed on laser axis between first reflector and first butt-end of laser at angle of 45 deg. to it axis, as well as third reflector disposed on axis drawn between point of intersection of beam splitter reflecting surface and laser axis perpendicular to this axis; beam splitter and third reflector are rigidly intercoupled and mounted on revolving flange whose axis is aligned with laser axis; it is set in rotary motion by means of motor drive, for instance that of frictional type, at frequency f ≥ 10 Hz mounted on positioner housing; reflecting surface of third reflector is tilted through angle β = 45° + α/4 to laser axis, where α is X-ray radiator angle of radiation; distance C between centers of beam splitter and third reflector is correlated with distance B along laser axis from center of first reflector to that of beam splitter by equation C=(A-B)·tg(α/2), where A is distance from X-ray radiator focus to first reflector center. This positioner incorporates provision for estimating X-rayed area of object and also for determining center of this area.

EFFECT: enlarged functional capabilities and facilitated determination of radiator-to-object distance.
