FIELD: x-ray technologies, possible use for orientation of x-ray emitter relatively to an object.
SUBSTANCE: in accordance to the invention, introduced additionally is second reflector, which is made semi-transparent and mounted on optical axis of objective of television system between that objective and first reflector, on an axis, passing through point of intersection of objective axis with second reflector perpendicularly to that axis at distance A from that point, circular matrix of micro-lasers is positioned, containing one central micro-laser, emission axis of which coincides with axis drawn from point of intersection of second reflector with objective axis, perpendicularly to that axis, and N≥8 micro-lasers, positioned symmetrically relatively to central micro-laser on circle D, axes of radiation of these micro-lasers in planes, formed by axes of micro-lasers and axis of central micro-laser, are inclined at angle α/2 to axis of central micro-laser, where α - angle of divergence of x-ray radiation beam, axes of micro-lasers, positioned on D diameter circle, intersect the axis of central micro-laser in point of intersection of second reflector with axis of objective, positioned at distance A from point of intersection of first reflector with x-ray beam axis, equal to distance from that point to focus of x-ray pipe of emitter along x-ray beam axis, diameter D of laser matrix is connected to distance A from it to point of intersection of objective axis to second reflector by ratio D=2·tg(α/2), in front of two micro-lasers, axes of which are mutually parallel and axes of x-ray beam, symmetrically identical cylindrical lenses are mounted with focal distances where d - diameter of micro-laser beams.
EFFECT: determining of zone of object, lit through by x-ray radiation, and also of the center of that zone.
