Abstract
The presampling modulation transfer function (MTF) can be determined by the edge spread function in which the sampling interval is narrower than the pixel-to-pixel interval from slight angled edge image. It is important that the precision of the presampling MTF depend on the precision of the edge angle. In this study, we have developed the automated method, which includes a precise edge angle determination process for the measurement of the presampling MTF.
