The mean-squared error between an object and image formed by scanning was used by Beall as a measure of the degree of fidelity of the image. A similar approach to the image transfer by fiber optics is presented. In this paper, the one-dimensional line-scan analysis proposed by Beall is extended to encompass a two-dimensional sampling process for evaluating the image transfer in a fiber bundle. Interesting results occur when the evaluation technique is extended to the comparison of the imaging properties of a static bundle and a bundle that is dynamically scanned. This analysis indicates that there is a significant difference of resolution between the static case and the dynamically scanned case. The difference is found to be largely determined by the fiber configuration within the bundle. Experimental results in the case of the static fiber will be presented.
