The hybrid luminescent device includes a phosphor screen disposed on an entrance face fiber optics scintillator which, in turn, may be removably coupled to a camera or like recording media. The hybrid luminescent device of the present invention is capable of providing enhanced radiation absorption efficiency, higher spatial resolution and enhanced brightness or luminescence output over that which is achievable by the phosphor screen and/or fiber optics scintillator when used separately as an intensifying screen for imaging of ionizing and/or penetrating radiation.Other References
