Abstract:

This thesis evaluates the effect of concurrent photon amplification CPA on Kodak Tri-X Pan emulsion in regard to image quality. The study evaluated detective quantum efficiency DQE, modulation transfer function MTF, and information content IC as a function of exposure in a comparison between normal exposure and CPA. The results showed CPA to enhance image quality relative to normal exposure at very low exposure levels. As the exposure was increased, normally exposed images became comparable and then exceeded CPA exposures in image quality. The exposure level at which normal exposure became preferential was distinct with each image quality measure. A computer program is included.
