Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 546850640
The aim of the project is the fundamental investigation of the propagation of non-classical light in volume-scattering media. In particular, coherent backscattering, angle-resolved reflection, and wavefront shaping are to be investigated experimentally and theoretically. For this purpose, optically and geometrically well characterized phantom media will be fabricated, in which the light propagation will be calculated on the basis of solutions of Maxwell's equations and their approximation, the radiative transfer equation, taking into account the quantum nature of non-classical light. This will allow, for the first time, absolute comparisons of experimental and theoretical results depending on the scattering and absorption properties of the phantoms used. The knowledge gained will be applied in a further experimental setup to quantitatively understand microscopy with non-classical light in scattering media, such as biological media, and to improve it, for example with regard to its spatial resolution. For this purpose, highly efficient single photon sources will be developed and employed for single molecule optical microscopy.
