FIELD: physics, measurement.
SUBSTANCE: multispectral digital photofluorographic device, which includes source of ionising radiation, luminescent screen, high-aperture lens and charge-coupled device matrix, which differs by the fact that in plane of luminescent screen from the side of radiator modulating mask is installed, which is made of heavy metal foil and includes several identical motives, every of which represents pseudo-random sequence of openings, at that light metal foil plate is placed between mask and luminescent screen.
EFFECT: creation of improved multispectral digital photofluorographic device.
