Abstract
An apparatus and method for radiographic image includes a plurality of light emitting diodes two of which produce light in the optical or visible wavelengths, another one of which produces light in an infrared wavelength so that pumping light can be supplied to a variety of radiographic substrate media. The pumping light is supplied to the medium by a plurality of optical fibers arranged in a linear array as the medium is scanned beneath the fibers. A second plurality of linear optical fibers picks up phosphorescent emissions from the radiographic medium due to the pumping light excitation and supplies the emissions to a photodiode or other optical receiver where the light intensity is translated into an electrical signal. The signal is sent to a processor which generates an image signal. The image signal may then be converted into an image representative of the latent x-ray image on the radiographic medium.
