Abstract
Disclosed is an imaging device of the type which, notably, associates a scintillator screen and a matrix of photosensitive elements. The invention particularly concerns means which can be used to reduce an active surface of a photosensitive element to a far greater extent than the quantity of light to which this photosensitive element is exposed. To this end, the scintillator has an input screen and an output screen, respectively applied to an input face and an output face of the scintillator, the output screen being provided with apertures that let through a light emitted by the scintillator, the apertures being placed in a matrix arrangement and indexed on the network of photosensitive elements.
