Maximum-likelihood estimation in ptychography in the presence of Poisson-Gaussian noise statistics
Optical measurements often exhibit mixed Poisson-Gaussian noise statistics, which hampers image quality, particularly under low signal-to-noise ratio (SNR) conditions.
Efficient and flexible approach to ptychography using an optimization framework based on automatic differentiation
Ptychography is a lensless imaging method that allows for wavefront sensing and phase-sensitive microscopy from a set of diffraction patterns.
