Abstract
Most methods for measuring the system response of image digitizers have involved an optical knife-edge. There are two reasons for this: first, high quality knife-edges are not difficult to obtain; and second, the one-dimensional impulse response of the system may be obtained by differentiating the response to a step function (which the knife-edge approximates).* The technique presented below uses a knife-edge scan in a slightly novel context to obtain the edge spread function (ESF) of image scanners. Traditional methods may then be used to obtain the line spread function (LSF) from the ESF.
