Gerchberg-Saxton algorithm (Tutorial)
Gerchberg-Saxton is a phase retrieval algorithm, which attempts to retrieve the phase corresponding to two intensity images taken in the near and far-field respectively. It can also be used for calculating computer-generated holograms (phase masks) that generate a desired intensity/field in the far-field (Fourier plane).
