Abstract
A light collector for collecting and detecting emitted light from a stimulable phosphor sheet includes a cylinder with an elliptical cross section having specularly reflective internal surfaces, a pair of plane mirrors at the ends of the cylinder, and a row of photodetectors located along one side of the cylinder in the vicinity of a focal line of the ellipse. The stimulable phosphor sheet is positioned in the vicinity of the other focal line of the ellipse, so that most the light emitted from the stimulable phosphor is reflected once from the elliptical reflector to the light detector.
