Generalized deterministic linear model for coherent diffractive imaging

A linear model for coherent diffractive imaging (CDI) is proposed herein. In this model, CDI expressed as a system of equations in the frequency domain an object and illumination. The can be directly determined to provide unique solution complex samples. method analytical straightforward does not require any approximation. simulation results demonstrate that valid all CDI-related methods, such traditional CDI, ptychography, modulation imaging, multiple-plane phase retrieval. relationship between convergence iterative retrieval discussed. This mathematical provides direct analyzing underlying physics used predict accuracy error applications, measurement metrology.
