RADIO-OPTICAL ENDOSCOPE Russian patent published in 2004 - IPC

FIELD: x-ray optics.

SUBSTANCE: case of endoscope has visual-optical channels for projecting object image to CCD-array. The channels are optically integrated by means of mirrors and prisms. Radio-optical channel has focon end of which is provided with roentgen-luminophor, fiber-optic regular braid, output focon which is integrated with its ends with braid and input fiber-optic spacer of electro-optical luminance amplifier, mirror and collimator lens. Visual-optical channel has lens, regular braid, eye-piece, illuminating braid and illuminating unit provided with lamp. There is optical attenuator installed in front of lamp. Endoscope additionally has two semitransparent mirrors made of acrylic plastic. First mirror is installed inside radio-optical channel at its input between first mirror and roentgen-luminophor of focon. Second mirror is installed at the output of endoscope on optical axis of lens which is installed in front of output end of image luminance amplifier. Collecting lens made of acrylic plastic is installed between first mirror and additional semitransparent mirror. Point diaphragm is installed in perpendicular to optical axis of lens. Point diaphragm is radiated by first additional light-emitting diode. Scale is installed in front of second additional semitransparent mirror. Scale is radiated by second additional light-emitting diode.

EFFECT: improved efficiency of application of endoscope.
