X-RAY OPTICAL ENDOSCOPE Russian patent published in 2010 - IPC G01N23/04 G01N21/01 A61B1/00 

FIELD: physics.

SUBSTANCE: X-ray optical endoscope has a housing inside of which there are optically interfaced X-ray and viewing optical channels for viewing the image of an object, the X-ray channel has a first focon with an X-ray fluorescent transducer at the input end, a second focon identical to the first whose output end is mated with the input fibre-optic washer of an image-intensifier tube, a first regular fibre-optic bundle which interfaces butt-ends of focons by smaller diametres, a first collimating lens whose focal plane coincides with the plane of the output fibre-optic washer of the image intensifier, and the optical axis is superimposed with its axis of symmetry and a first semitransparent mirror mounted on that axis at an angle of 45°, wherein the endoscope also includes an annular matrix of N>=8 microlasers in front of the X-ray fluorescent transducer concentrically with the transducer outside the zone of propagation of the information-bearing part of the stream of X-rays, optical axes of the microlasers are parallel each other and axis of the first focon and they lie symmetrically on a circle of diametre Dl, through which an annular structure of laser spots forms on the object, where the diametre Dl remains constant with variation of distance from the object to the endoscope and is equal to the diametre of the zone of the object illuminated by X-rays.

EFFECT: possibility of matching considerably different characteristics of X-ray and optical channels.
