1. 1. 2D & 3D phase retrieval for propagation-based X-ray phase-contrast tomography

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Philip Stjärneblad; [2021]
   Keywords : Propagation-based X-ray phase-contrast tomography; PB-PCT; Propagation-based X-ray phase-contrast Imaging; PB-PCI; 2d phase retrieval; 3d phase retrieval; TIE; sinogram consistency; reconstruction artefacts; Science General;

   Abstract : Propagation-based X-ray phase-contrast tomography is a 3d imaging technique that utilizes two-dimensional projections from different angular views $\theta =[0,\pi]$ to reconstruct the 3D object information. The phase-contrast allows for higher feature contrast than conventional transmission tomography, as the phase interference gives rise to a sharp edge contrast. READ MORE

3. 2. Calibration of Quenching for laser-induced fluorescence of CO₂ at 2.7 μm

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : Philip Stjärneblad; [2019]
   Keywords : Laser-induced fluorescence; CO oxidation; Catalysis; Fluorescence quenching; Calibration; Physics and Astronomy;

   Abstract : Knowledge about the gas-phase close to an active catalyst is essential in order to understand the properties of the catalytic reaction process. By the use of planar laser-induced fluorescence (PLIF), the gas-phase can be visualized with high spatial and temporal resolution without affecting the catalyst. READ MORE
