Iterative phase retrieval algorithm for space-variant PSFs in optical systems with aberrations

Iterative phase retrieval (IPR) algorithms are widely used in digital optics because of their efficiency and simplicity. Conventionally, these algorithms do not consider aberrations as they assume an ideal, aberration-free optical system. Here, we propose modified iterative phase retrieval algorithms that take into account the space-invariant (SI-PSF) and space-variant point spread function (SV-PSF) of the optical system.
