Abstract
The spatial resolution is described in terms of the modulation transfer function (HTF). We will analyze the influence of the focal spot size, the movement of the object, and the resolution of the receptor. The quality of images can only be properly described if the visual system is taken into account. Consequently, we base the MTF quality criterion on the visual detection of the corresponding line-spread and edge-spread images. It appears that there is a positive correlation between this psychophysical quality and the spatial frequency for which the modulation transfer equals 0.25. This finding enables a set of characteristic parameters and nomograms to be developed, which combine the lucidity of the "unsharpness" concept with the exactness of the description by the modulation transfer function,
