Detecting Infrared Single Photons with Near-Unity System Detection Efficiency
Jin Chang, Johannes W. N. Los, Jaime Oscar Tenorio-Pearl +9
Single photon detectors are indispensable tools in optics, from fundamental measurements to quantum information processing. The ability of superconducting nanowire single photon de…
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…
