Abstract

An automated Ronchigram analysis system capable of analyzing cross grating ronchigrams, produced by a single channel Ronchi system, is being developed. Because of the complexity of the Ronchigrams it is necessary to separate the vertical and horizontal components. Two basic approaches of component separation, Fourier decomposition and differentiation, are described and evaluated.
