Abstract:
Measuring device of measuring exposure of a solid-state image detector, the image detector having a first face exposed to ionising radiation of the image and letting unabsorbed ionising radiation pass through a second face opposite said first face,wherein the measuring device includes at least one optical scintillating fiber adapted for receiving the unabsorbed ionising radiation through a lateral surface of said optical fiber, converting in terms of wavelength said unabsorbed ionising radiation into a visible or near-visible radiation, and emitting said visible or near-visible radiation, which is representative of the unabsorbed ionising radiation, towards a detection device to produce a signal representative of the exposure of the image detector, and wherein the measuring device is configured to be placed closed to the second face of the image detector and to be exposed to the unabsorbed ionising radiation.
