Cramér-Rao lower bound and maximum-likelihood estimation in ptychography with Poisson noise

X Wei, HP Urbach, WMJ Coene - Physical Review A, 2020 - APS
We investigate the performance of ptychography with noisy data by analyzing the Cramér-
Rao lower bound. The lower bound of ptychography is derived and numerically computed …

Ptychography with multiple wavelength illumination

X Wei, P Urbach - Optics express, 2019 - opg.optica.org
For performing phase retrieval in the extreme ultraviolet (EUV) regime more efficiently,
develo** polychromatic ptychography is desirable. As an alternative to the existing …
