Nanoparticle Interferometer by Throw and Catch

Atoms
Matter wave interferometry with increasingly larger masses could pave the way to understanding the nature of wavefunction collapse, the quantum to classical transition, or even how an object in a spatial superposition interacts with its gravitational ...

Non-iterative Directional Dark-field Tomography

Scientific Reports, 2017
Dark-field imaging is a scattering-based X-ray imaging method that can be performed with laboratory X-ray tubes. The possibility to obtain information about unresolvable structures has already seen a lot of interest for both medical and material science ...

Thermal deformation compensation scheme to the sub‐nanometre level of a piezoelectric offset mirror for MHz repetition rate free‐electron laser

Journal of Synchrotron Radiation, Volume 32, Issue 1, Page 46-56, January 2025.
A compensation scheme has been developed to control thermal deformation of offset mirrors used in MHz repetition rate free‐electron lasers to sub‐nanometre level. This approach employs a piezoelectric deformable mirror, utilizes finite‐element analysis for simulation and post‐processing verification, and integrates a differential evolution algorithm ...

Isotope-selective high-order interferometry with large organic molecules in free fall

New Journal of Physics, 2018
Interferometry in the time domain has proven valuable for matter-wave based measurements. This concept has recently been generalized to cold molecular clusters using short-pulse standing light waves which realized photo-depletion gratings, arranged in a ...

Bio‐Engineering Yeast Cells Biolenses by Reshaping Intracellular Vacuoles

Advanced Optical Materials, Volume 12, Issue 18, June 26, 2024.
Achieving tunable biolens effects in single cells by altering their internal structures is feasible. Particularly, hypotonic conditions prompt reshaping of intracellular vacuoles in yeast cells. Utilizing Tomographic Phase Imaging Flow Cytometry, 3D refractive index tomograms of suspended cells are captured, thus enabling in‐depth characterizations ...

Laboratory-based X-ray phase-imaging scanner using Talbot-Lau interferometer for non-destructive testing

Scientific Reports, 2017
An X-ray Talbot-Lau interferometer scanning setup consisting of three transmission gratings, a laboratory-based X-ray source that emits X-rays vertically, and an image detector on the top has been developed for the application of X-ray phase imaging to ...

Immersion microlithography at 193 nm with a Talbot prism interferometer [PDF]

SPIE Proceedings, 2004
A Talbot interference immersion lithography system that uses a compact prism is presented. The use of a compact prism allows the formation of a fluid layer between the optics and the image plane, enhancing the resolution. The reduced dimensions of the system alleviate coherence requirements placed on the source, allowing the use of a compact ArF ...

A Multicompartment Assessment of Microplastic Contamination in Semi‐remote Boreal Lakes

Environmental Toxicology and Chemistry, Volume 43, Issue 5, Page 999-1011, May 2024.
Abstract Microplastic contamination is ubiquitous across the globe, even in remote locations. Still, the sources and pathways of microplastics to such locations are largely unknown. To investigate microplastic contamination in a semi‐remote location, we measured microplastic concentrations in nine oligotrophic lakes within and around the International ...

Advancing research and education with simple setup Talbot-Lau-Interferometers

e-Journal of Nondestructive Testing, 2023
Grating based interferometry is a widely established technique used for various applications in X-ray imaging, from materials science [1,2] to medical diagnosis [3,4]. Talbot-Lau-Interferometers are especially promising for laboratory-based setups. By introducing a source grating into the optical setup, requirements on the spatial coherence of the ...
