Abstract
OSL (optically stimulated luminescence/photostimulated luminescence-PSL-) storage phosphors imaging plates are well known to present advantages in terms of sensitivity, spatial resolution, linearity, and signal dynamics in comparison with classical 'scintillating screen- film' packs for radiology (soft x-rays). Are these OSL so useful for high energy (MeV) radiography (non destructive testing or flash radiography)? Experiments show that only linearity and dynamics are better than those of screen-film cells. We present some improvement directions for this promising imager: metallic screens, thicker OSL plate, densification, sensitization methods.
