講座內容:
In this seminar I will review various optical methods implemented in my lab, over the years, for the non-invasive and in-line characterization of micro and nanoparticles encountered in various systems of scientific and industrial interest: two and multiphase flows, colloids and suspensions, dusty and fusion plasmas… A special emphasis will be put on their limitations, attributable to the models (light scattering theories and approximations, morphological, dispersion) and to the signals analysis (regularization and minimization problems, computational resources, noise…). Among the various techniques that will be discussed and illustrated there will be spectral, as well as small to large angle scattering and interferometric ones.
