      abstract     = {Conventional seismic imaging methods utilise a small
                      portion of the information in the seismic data we obtain.
                      Most methods analyse their arrival times or specific signal
                      amplitudes only. In this report we further develop and apply
                      a new seismic inversion and imaging technique that uses the
                      full information content of the seismic recordings. Full
                      waveform inversion (FWI) is an algorithm that accounts for
                      the full seismic waveform. It iteratively retrieves
                      multiparameter physical models of the material by
                      numerically solving the wave equation and optimisation
                      problem. FWI is currently a cutting-edge seismic inversion
                      and imaging technique that enables to exploit the full
                      information contained in the seismic waveforms over a broad
                      range of frequencies and apertures for an improved
                      estimation of physical parameters. It allows for a mapping
                      of structures on spatial scales down to approximately half
                      of the seismic wavelength, hence providing a tremendous
                      improvement of resolution compared to travel-time tomography
                      based on ray-theory. We especially focus on the applications
                      of FWI on two different scales, including near-surface scale
                      which extends from Earth’s free surface to a depth around
                      10 meters and laboratory scale which targets on material
                      from a few millimetre to less than one meter. Numerical
                      tests and real-world applications are used to show the high
                      resolution of FWI in reconstructing physical properties of
                      the earth model and artificial material.},
