HoToPy: A toolbox for X-ray holo-tomography in Python
Jens Lucht, Paul Meyer, Leon Merten Lohse +1
We present a Python toolbox for holographic and tomographic X-ray imaging. It comprises a collection of phase retrieval algorithms for the deeply holographic and direct contrast im…
Energy Time Ptychography for one-dimensional phase retrieval
Ankita Negi, Leon Merten Lohse, Sven Velten +9
Phase retrieval is at the heart of adaptive optics and modern high-resolution imaging. Without phase information, optical systems are limited to intensity-only measurements, hinder…
Interferometric measurement of nuclear resonant phase shift with a nanoscale Young double waveguide
Leon M. Lohse, Ankita Negi, Markus Osterhoff +6
The phase shift of an electromagnetic wave, imprinted by its interaction with atomic scatterers, is a central quantity in optics and photonics. In particular, it encodes informatio…
Quantum Nanophotonics with Energetic Particles:X-rays and Free Electrons
Xihang Shi, Wen Wei Lee, Aviv Karnieli +7
Rapid progress in precision nanofabrication and atomic design over the past 50 years has ushered in a succession of transformative eras for molding the generation and flow of light…
