“Seeing” Beneath the Clouds—Machine‐Learning‐Based Reconstruction of North African Dust Plumes

AGU Advances, Volume 5, Issue 1, February 2024.
Abstract Mineral dust is one of the most abundant atmospheric aerosol species and has various far‐reaching effects on the climate system and adverse impacts on air quality. Satellite observations can provide spatio‐temporal information on dust emission and transport pathways.

Temporal Talbot interferometer of a strongly interacting molecular Bose-Einstein condensate

Physical Review A
Talbot interferometer, as a periodic reproduction of momentum distribution in the time domain, finds significant applications in multiple research. The inter-particle interactions during the diffraction and interference process introduce numerous many-body physics problems, leading to unconventional interference characteristics.

A study of optical vortices inside the Talbot interferometer

, 2015
The optical Talbot interferometer has been used to explore the topological charges of optical vortices. We recorded the self-imaging of a diffraction grating in the near-field regime with the optical vortex of several topological charges. Our twisted light was generated by a spatial light modulator (SLM).

Flexible X-ray Talbot-Lau interferometer and its theory

Optics Express
X-ray Talbot-Lau interferometer, offering multi-contrast for the imaged objects, has shown powerful capacity in imaging biological soft tissues, low density materials, etc. However, the length of the system is constant, which limits its applications. Here, we establish a new X-ray Talbot-Lau interferometer theory to achieve a flexible phase contrast ...

Realisierung eines Talbot-Lau-Interferometers an Mikrofokusröhren für materialwissenschaftliche Tomografieanwendungen

, 2016
Durch Verwendung eines Talbot-Lau Interferometers können in der Computertomografie Aufnahmen in Phasen- und Dunkelfeldkontrast dargestellt werden. Dies wurde bereits anhand mehrerer Anwendungen im medizinischen Bereich demonstriert. Das Ziel dieser Arbeit war einen Talbot-Lau Interferometer mit einer Transmissions-Mikrofokus-Röntgenröhre umzusetzen und
