Parameter retrieval methods in ptychography
Xukang Wei, H. Paul Urbach, Peter van der Walle +1
We present a parameter retrieval method which combines ptychography and additional prior knowledge about the object. The proposed method is applied to two applications: (1) paramet…
The CRLB and Maximum likelihood in ptychography with Poisson noise
Xukang Wei, H. Paul Urbach
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 for both…
Lateral position correction in ptychography with sub-pixel accuracy
P. Dwivedi, A. P. Konijnenberg, S. F. Pereira +1
Ptychography, a form of Coherent Diffractive Imaging, is used with short wavelengths (e.g. X-rays, electron beams) to achieve high-resolution image reconstructions. One of the limi…
