When optical designers attempt to compare the performance of optical systems, a commonly used measure is the modulation transfer function (MTF). MTF is used for components as simple as a spherical singlet lens to those as complex as a multi-element telecentric imaging lens assembly.

Webdard Fast Fourier Transform (FFT). Instead, a non-uniform FFT can be used to evaluate the measurement equation, where an FFT is applied, and the visibilities are interpolated off of the FFT grid. This is known as the non-uniform FFT (NUFFT) but is commonly known as degridding in radio astronomy (Fessler & Sutton2003; Thompson et al.2008).
