Gerchberg–Saxton algorithm
Summary
The Gerchberg–Saxton algorithm is an iterative method that finds a phase for a wave from its amplitude in two planes. The two planes are linked by a Fourier transform. It goes back and forth between the two planes and in each plane keeps the current phase but replaces the amplitude by the measured one. R. W. Gerchberg and W. O. Saxton published it in 1972 for electron microscopy. It is the starting point of many phase retrieval methods and is used to design phase holograms for beam shaping.
