The position is fully funded for UK and EU applicants, who have a background in computer science, applied maths or engineering. Description: Chemical Species Tomography (CST) is a diagnostic modality for gases and other optically transparent fluids, based on measurements and models of spectroscopic absorption and laser attenuation. Although still in its early stages of development, CST is considered as an effective solution for imaging in-situ the concentration of chemical species such as pollutants in the exhaust plumes of gas turbines, aviation engines and power generators. Its application in the aerospace sector is motivated by the need to provide combustion diagnostics for jet engines in order to prevent malfunction and failure. At the same time, CST provides an adjunct tool for assessing the performance and environmental footprint of alternative, cleaner aviation fuels. The focus of the project is to investigate the properties of the inverse problem and develop image reconstruction algorithms that are better equipped to deal with fitting model parameters with a relatively few data. Extensions to this work are also applicable in other application areas such as spectral X-ray tomography from limited angle acquisitions. The project will benefit from the collaboration with academics and researchers within an existing network of collaborators from a number of UK universities, as well as national and international industrial partners in the photonics, aviation and fuels sectors.
