Abstract

Iterative phase retrieval algorithms are widely used in digital optics for 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 and space-variant point spread function of the optical system.
