WebMay 22, 2011 · The optical FFT is implemented using a single DI realizing a two-point optical FFT 15. This is preferred over the eight-point FFT used in the 10.8 Tbit s −1 demonstration because of its simplicity. Fourier optics is used in the field of optical information processing, the staple of which is the classical 4F processor. The Fourier transform properties of a lens provide numerous applications in optical signal processing such as spatial filtering, optical correlation and computer generated holograms.

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).
