PhD : Computational imaging in complex media

Due to its non-invasive nature and micrometric resolution, optical microscopy is a key tool for observing living samples at the cellular level. However, scattering and distortion caused by the inhomogeneities of biological tissues limit the depth at which an image can be obtained. This major problem has stimulated a great deal of research over the last twenty years, with numerical processing playing an increasingly important role in the image formation.
Our team is specialised in computational imaging. The latter requires an accurate modeling of the link between the recorded data and the sample and sophisticated inversion techniques for recovering an estimation of the sample from the data. In this context, we have shown that multiple scattering, which is usually detrimental to the image formation could be used to improve the spatial resolution of the imager.
