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 projecting images of an object onto a CCD matrix of a television system which forms an image on a monitor, wherein the X-ray channel has a focon with an X-ray phosphor at its input end, a first fibre-optic regular bundle, a first collimating lens with focal distance F1, whose focal plane coincides with the output end of this bundle and a first mirror installed on the optical axis of the first collimating lens at an angle of 45°, wherein the endoscope also includes an annular matrix of N>8 microlasers placed symmetrically about the axis of the focon on a circle having diametre D equal to the diametre of the input end of the focon. Optical axes of the microlasers are parallel each other and the axis of the focon, owing to which they form an annular structure of laser spots of diametre D on the object, where the value D remains constant with variation of distance from the object to the endoscope.

EFFECT: possibility of matching considerably different characteristics of X-ray and optical channels, high image quality, reduced weight and size of the device.
