Abstract
A statistical analysis of degradation in a scanned image has been carried out by Beall. (Ref. 1) In the above analysis, the mean-squared value of the error function between the object and image was used as a measure of the degree of fidelity in the image, and numerical data have been published for several particular cases. A similar approach to image transfer in optical fiber bundles 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 which is scanned dynamically. (Ref. 2) This analysis indicated that there is a significant difference in 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 bundle will be presented.
