Characterizing of complex random media and biologigal tissue with self-consistent quantum field theory — Andreas Lubatsch1 and •Regine Frank2,3 — 1Physikalisches Institut, Rheinische Friedrich Wilhelms Universitaet Bonn — 2College of Biomedical Sciences, Larkin University, Miami, Florida, USA — 3Donostia International Physics Center, 20018 Donostia-San Sebastian, Spain
We present a quantum field theoretical method for characterizing disordered complex media with short laser pulses and (OCT). We introduce weighted essentially non-oszillatory solvers (WENO) for the analysis of highly nonlinear and discontinuous processes including interference effects and Anderson localization of light in time-of-flight (ToF) and pump-probe experiments. The results are a measure of the coherence of multiple scattering photons in passive matter as well as in soft matter and biological tissue.
