Title: Prediction of cut-off frequency from the maximum slope of a transmittance scan of an ideal edge
Author: Ewbank, Dale
Abstract: This study has empirically shown that the maximum slope of an ideal edge scan in transmittance versus position is an excellent indicator of the cut-off frequency at which a microdensitometer system's modulation transfer function goes to zero. It was found that numerical aperture of collection objective, scanning slit width and alignment, system focus, and sampling interval are parameters which must be carefully chosen and set-up when implementing or using this slope technique to check system performance.
