    On the conditional equivalence of phase retrieval algorithms

    Jakob Schroeder, Andreas Döpp

    physics.optics · cs.LG

    Phase retrieval - recovering a complex-valued field from intensity measurements - is typically solved using variants of the Gerchberg-Saxton (GS) algorithm, understood as alternating projections between measurement planes. Meanwhile, modern computational imaging increasingly relies on gradient-based optimization and automatic differentiation. Here we show that these two approaches are mathematically identical: the GS magnitude replacement...
