Research output: Contribution to journalArticle

Abstract

An inversion algorithm, involving a linear least-squares method, is developed to analyze the intensity data obtained by application of the traveling knife-edge method. Through use of simulated intensity data, diameters can be measured to an accuracy of 0. 05%. The method also yields good results when it is applied to He-Ne laser beam data.
