Webcomparisons of using the LSF and ESF to calculate MTF as well as the use of super-resolution to overcome aliasing present in systems where the detector under-samples the optical system response [1]. In the current study, the point of interest is in making changes to how the Fourier transform is used to extract a MTF from the LSF. The methods WebFunction, or LSF. It can be shown that the MTF, which is defined in terms of sine-wave targets, is actually the Fourier Transform of the LSF curve. Once the LSF measured, the MTF can be calculated in just a few milliseconds using a modern desktop computer. Theory and Measurement of MTF .
