2. 1. Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications

   Author : Rikard Wellander; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Post injection; Structured illumination; Mie scattering; Dense sprays; Extinction coefficient; Signal attenuation; Laser extinction; Multiple scattering; Scattering measurements; Planar laser induced fluorescence; Time resolved; Imaging through turbulent media; Three-dimensional image acquisition; Diesel particulate filter regeneration; Wall impingent; Biodiesel; LII; Large-bore gas Engine; Pre-chamber ignition; Fysicumarkivet A:2014:Wellander;

   Abstract : Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. READ MORE

4. 2. Laser Diagnostics in Combustion - Elastic Scattering and Picosecond Laser-Induced Fluorescence

   Abstract : Elastic scattering and the Lorenz-Mie (LM) theory in particular is used for the characterization of sub-micron- and micron-sized droplets of organic fuels in sprays and aerosols. Calculations on the Lorenz- Mie theory show that backward-sideward scattered visible radiation can be used for unambiguous detection of ensembles of homogeneous droplets of organic substances with diameters around 1 micrometer (size parameter between 2 and 6).

   Abstract : Roll-to-roll manufacturing of micro components based on advanced printing, structuring and lamination of ceramic tapes is rapidly progressing. This large-scale and cost-effective manufacturing process of ceramic micro devices is however prone to hide defects within the visually opaque tape stacks. READ MORE

7. 5. Multi­-Scattering: Computational light transport in turbid media

   Author : Joakim Jönsson; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte carlo simulations; scattering in tissues; particulate scattering; GPU; CUDA; Fysicumarkivet A:2021:Jönsson;

   Abstract : This thesis presents and describes the development of an online freely accessible software called Multi-Scattering for the computational modeling of light propagation in scattering and absorbing media. The model is based on the use of the Monte Carlo method, where billions of photon packets are being launched and tracked through simulated cubic volumes. READ MORE
