LASER LOCALIZER FOR X-RAY EMITTER Russian patent published in 2008 - IPC H05G1/00 

FIELD: x-ray technologies, possible use for orientation of x-ray emitter relatively to an object.

SUBSTANCE: in accordance to the invention, introduced additionally are cylindrical lens, mounted on laser axis between its second emitting end and second reflector and generating flat divergent light beam, expanding perpendicularly to a plane formed by axes of laser and x-ray beam, light divider, mounted on laser axis between its first emitting end and first reflector, objective with focal distance f', mounted on the axis passing through point of intersection of light divider with laser axis perpendicularly to that axis, narrowband light filter, mounted in front of an objective, spectral throughput maximum of which coincides with wave length of laser radiation for increasing contrast of image of laser spots on an object, charge-coupled matrix with size A×A, mounted in focal plane of objective, television monitor for observation of control object and positioning laser spots on it, and linear scale, mounted directly on the monitor screen with size K×K and digitized in units of distance from object to x-ray emitter, indications from which are read by means of image of vertical laser stroke on a screen, position of which is proportional to distance from object to x-ray emitter.

EFFECT: simplified design of device and its operation, receipt of current information about distance from object to x-ray emitter.
