Video aided 1D Extinction – a novel technique for nanodust density measurements — •Andreas Petersen, Alexander Schmitz, and Franko Greiner — Institut für Experimentelle und Angewandte Physik, Christian-Albrechts-Universität zu Kiel

Extinction measurements are the basis of dust density diagnostics in nanodusty plasmas. Standard techniques are computed tomography (CT) for arbitrarily shaped clouds and Abel inversion (AIN) for cylindrically symmetric dust clouds. For density measurements in a plasma chamber, where no full optical access is possible, we developed a new technique, which utilizes a laser stripe, two CMOS line cameras and one 2D camera. The VaEM method can be used to measure the dust density along a slice through the dust cloud and does not require cylindrical symmetry.
