MULTISPECTRAL X-RAY SCANNER Russian patent published in 2008 - IPC G03G13/54 G01N23/83 

FIELD: physics, measurement.

SUBSTANCE: multispectral X-ray scanner that contains source of ionising radiation, collimator in the form of longitudinal circuit intended for creation of flat radiation beam and device for registration of radiation beam, which includes electronics for data reading and processing, luminescent screen and one bar of photoreceiving modules that contain photodiodes that are optically conjugated with luminescent screen, which differs by the fact that device of radiation beam registration contains at least two luminescent screens that are located in radiation beam and separated from each other with complementary filter in the form of two plates made of light metal foil and plate made of heavy metal foil installed between them, and at least two bars of photoreceiving modules, which are installed outside flat radiation beam, every of which is optically conjugated with one luminescent screen.

EFFECT: expansion of X-ray device operation spectral range and division of this range into several spectral zones.
