The 'star' is the zero-order diffraction peak.]] The '''Gerchberg–Saxton (GS) algorithm''' is an iterative [[algorithm]] for retrieving the phase of a pair of light distributions (or any other mathematically valid distribution) related via a propagating function, such as the [[Fourier transform]], if their intensities at their respective optical planes are known.
