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 in which there is a focon with an X-ray fluorescent transducer at the input end, a CCD matrix in whose A×A bit map the image of the output end of the focon is completely inscribed and a television monitor for viewing X-ray images formed on said matrix, wherein the endoscope also has a colour television camera having a lens with focal distance F and a CCD matrix with an A×A bit map and an annular structure of N>8 microlasers whose axes are parallel to each other and axis of the focon, lying symmetrically about the input end of the focon on a circle of diametre D. The colour television camera is mounted at the centre of the input end of the focon or lies outside its limits. The focal distance of the lens is such that the image of the annular structure of laser spots can be completely inscribed in the bit map of that camera. The object is illuminated with a light-emitting diode with controlled brightness and colour index of radiation and in a certain way, with given angle of radiation, dimensions of defects are measured using a standard metric scale with a certain division value on the screen of the monitor.

EFFECT: higher matching of characteristics of X-ray and optical channels, reduced wearing of the semitransparent mirror.
