Paper Abstract

For years there has been a dichotomy within the test community about imaging sensor resolution figures of merit; one camp favoring the modulation transfer function (MTF) while the other prefers the minimum resolvable contrast (MRC). This presentation will attempts to bridge the gap between these two test approaches and describe how rigorous mathematical techniques might be applied to test data reduction in order to streamline the test process. We can superimpose the MTF and normalized noise curves into one 3 dimensional graph. Through Fourier and statistical analysis, a streamlined test approach and objective analysis is now possible. The potential for repeatability and cost savings can be realized through a two phased test procedure which anticipates these powerful analysis tools.
