Description: The quality of noisy images can be improved by summing several simular but statistically independent images that have been obtained either using a series of fluors in a stack intercepting the radiation from a single pinhole or by using multiple pinhole arrays or other coded apertures. An optical method of performing this addition is being explored for fuel pin imaging, and is presented here along with experimental results. In addition, the extension of this method to the simultaneous display of depth planes of a three-dimensional source is discussed.
