Abstract

Accurate measurement of the MTF for discrete imaging system can be obtained by viewing a known frequency target. A slit target is frequently used to measure the MTF for an imaging system. Usually we have 4 methods to measure the MTF for a discrete imaging system using a slit. But for the discrete imaging systems of under sampling that is difficult to reproduce this type of target properly since frequencies above Nyquist are folded into those below Nyquist, resulting in aliasing effect. To decrease the aliasing problem, we have introduced a "super resolution technique" to our measurement, which gives MTF values both above and below Nyquist more accurately.
