Abstract

High efficiency detection of stimulated emissions from photostimulable storage phosphors requires a specialized class of collector design. In addition to collecting as many stimulated photon emissions as possible, the design must minimize the probability of secondary stimulated emissions. The latter, resulting from the stimulating photons, originally scattered by the storage phosphor, whereby reflection, find a secondary path back to the storage phosphor and strike it at a location other than that of the scanning beam. These secondary emissions are referred to as flare light, and will degrade the MTF of the system. Eastman Kodak Company has developed and patented collector designs that are highly suitable for use in computed radiography scanner systems. The design and performance characteristics of this class of collector design will be presented.
