X-Ray Phase Contrast Imaging by Talbot-Lau Interferometer Without Phase-Stepping Device

IEEE Photonics Technology Letters, 2018
A new X-ray phase-contrast imaging on Talbot-Lau interferometer without phase-stepping device is proposed. A new analyzer grating is designed to replace the existing analyzer grating and scintillation conversion screen in the X-ray imaging system which is interlaced by the low-energy grid bars and the high-energy grid bars.

A laser frequency and power control system in an atomic Talbot-Lau interferometer

SPIE Proceedings, 2013
The importance of atom interferometers that have high sensitivity and super precision is well recognized in the fields of rotation sensing, inertial and gravitational forces sensing, relativity tests, and other precision measures. So many researchers are absorbed in atom interferometers.

Detection of early pulmonary emphysema by multi‐contrast x‐ray Talbot‐Lau interferometer

Medical Physics
AbstractBackgroundPulmonary emphysema is a part of chronic obstructive pulmonary disease, which is an irreversible chronic respiratory disease. In order to avoid further damage to lung tissue, early diagnosis and treatment of pulmonary emphysema is essential.PurposeEarly pulmonary emphysema diagnosis is difficult with conventional radiographic imaging.

Absorption imaging performance in a future Talbot-Lau interferometer based breast imaging system

SPIE Proceedings, 2015
A grating-based x-ray multi-contrast imaging system integrates a source grating G0, a diffraction grating G1, and an analyzer grating G2 into a conventional x-ray imaging system to generate images with three contrast mechanisms: absorption contrast, differential phase contrast, and dark field contrast.

Deflectometry in a Kapitza-Dirac-Talbot-Lau interferometer for matter waves

2013
This thesis treats deflectometry in a matter wave interferometer for neutral molecules. Deflection of beams of atoms and nanoparticles in the gas phase by inhomogeneous static electric and magnetic fields is used to determine their properties. Interferometers enhance the sensitivity of deflection experiments by orders of magnitude.

Computer control and data acquisition for the Kapitza-Dirac-Talbot-Lau interferometer

2018
Der Übergang von der klassischen Physik unserer Alltagswelt zur Quantenmechanik wirft bisher noch mehr Fragen auf, als es Antworten gibt. Ein vielversprechender Weg, um dem Mysterium ein Stück näher zu kommen, ist die Materiewelleninterferometrie mit Molekülen, da sich Quantenphänome anhand makroskopischer, komplexer Teilchen aufzeigen lassen.
