Abstract
The modulation transfer function (MTF) of optical systems is often derived by taking the Fourier transform (FT) of a measured line spread function. Recently, methods of performing Fourier transforms that are common in infrared spectroscopy have been applied to MTF calculations. Proper apodization and phase correction have been shown to improve MTF calculations in optical systems. In this paper these methods as well as another filtering algorithm based on phase are applied to under-sampled optical systems. Results, both with and without the additional processing are presented and the differences are discussed.
