Abstract

Many methods for the measuring of optical transfer function (OTF) have bee ki studied in the last two decades 11. The one dimensional OTF is obtained in the large majority of these methods since the spatial frequ-ency is scanned temporaly at a fixed azimuth. One can recognize the two-dimensional transfer function only after knowing the one-dimensional OTF along every discretely sampled azimuth. Only a few instruments have been developed for measuring both of modu-lation and phase transfer function, MTF and PTF, because the former is more important than the latter.
