Paper Abstract

After a short summary, the used measurement methods of modulation transfer function in the Physikalisch-Technische Bundesanstalt (PTB) are described. The experience and the difference of the methods regarding measuring time, their sources of error as well as the attainable accuracy are discussed. Furtheron a simple program to calculate the otf from lens data under consideration of the dif-fraction is explained and the results of the calculated otf compared with the experimental otf-values are given and the differences between them are shown. Finally, the advantage to use the otf in order to derive quality criteria of the image performance is emphasized in spite of some shortcomings resulting from the difficulties of the mostly used lenses and measuring devices.
