Abstract
An imaging system intended for imaging fast-moving objects, comprising an X-ray source, a scintillating screen, a shutter and a detector of the beam emitted by the shutter, and a processing unit connected to the detector, where the shutter is positioned between the scintillator screen and the detector, and a support for the object to be observed is positioned downstream from the X-ray source and upstream from the scintillator screen, where the shutter is a shutter which can be controlled at high frequencies, for example higher than approximately 1 kHz, where the shutter is fixed and the transmission of the signal originating from the scintillator screen towards the detector is controlled by electrical polarisation means controlled by a control unit.
Claims26
A system for imaging objects comprising at least one fixed portion and at least one moving portion, where the fixed and moving portions move relatively rapidly, and where the system comprises:
- an X-ray source,
- a scintillator screen,
- a fixed shutter,
- a detector of the beam emitted by the shutter, the shutter being positioned between the scintillator screen and the detector,
- a processing unit connected to the detector,
- a support for the object to be observed positioned downstream from the X-ray source and upstream from the scintillator screen,
- the shutter being a shutter which can be controlled at high frequencies and the transmission of the signal originating from the scintillator screen towards the detector is controlled by electrical polariser controlled by a control unit,
- an actuator of said object, so as to cause the moving portion to move relative to the fixed portion.
