X-RAY-OPTICAL ENDOSCOPE Russian patent published in 2009 - IPC G01N23/04 G01N21/01 A61B1/00 

FIELD: physics; optics.

SUBSTANCE: invention relates to detecting flaws in objects in difficult to access cavities. A device for complex X-ray and visual inspection of objects inside difficult to access cavities has a housing inside of which there are optically interfaced X-ray-optical and visual-optical channels for projecting the image of the object onto a CCD matrix of a television system, which forms an image on a monitor. Inside the housing there is also a fourth lens, the optical axis of which is parallel to the optical axis of the focusing cone and lies at a distance R from it. The focusing cone and the fourth lens are fitted with possibility of mutual displacement without violating parallel alignment of their optical axes within the limits of value R and successive fixation in positions for which the centre of the input face of the focusing cone and the centre of image of the fourth lens are superposed with the centre of the regular optical fibre bundle of the X-ray-optical channel, and in front of a broadband light source of the visual-optical channel, which emits in the visible and ultraviolet spectra, a filter is placed with possibility of input-output from the radiation flux, where the filter selects from the radiation spectrum of this source waves in the UV range, which excite photoluminescence in the penetrant used in luminescent defectoscopy.

EFFECT: possibility of inspecting objects in dark conditions.
