LASER LOCALIZER FOR X-RAY EMITTER Russian patent published in 2007 - IPC H05G1/00 

FIELD: technology for orientation of x-ray emitter relatively to object.

SUBSTANCE: in accordance to invention device additionally contains narrowband light filter, pass band of which coincides with laser radiation wave length, mounted in front of objective of television system, for measuring distance from object to x-ray emitter laser range finder is used, mounted in the body of localizer, ray of which expands by means of first mirror in direction, coinciding with axis of x-ray beam and generates laser spot on object, position of which matches with point of intersection of object with axis of x-ray beam, axes of lasers of circular matrix in planes, formed by axes of lasers and axis of laser of range finder system, are inclined to axis of range finder laser at angles α/2, where α angle of radiation of x-ray emitter, converge in one point at distance B from matrix body on axis of range finder laser, positioned at distance A from point of intersection of first mirror with axis of x-ray beam, equal to distance from this point to focus of x-ray pipe along the axis of x-ray beam, equal to distance from this point to focus of x-ray tube along axis of x-ray beam and after reflection from first mirror expand in form of conical beam of N rays, where N - number of lasers of circular matrix, forming circular structure of N spots on the surface of object, symmetric relatively to central spot, formed by range finder laser on the object, while diameter of this structure matches with size of zone of object lit through by x-ray radiation.

EFFECT: increased contrast of laser spot on object under conditions of sun flare, and also increased precision when determining distance from object to x-ray emitter.
