Diagnostic Methods in Dusty Plasmas

The dust size, the interparticle distance and the time scales associated with the particle motion are ideally suited to study the dusty plasmas by optical techniques. Here, we like to review different diagnostic methods (video microscopy, scanning microscopy, holography, stereoscopy) to measure the structure and dynamics of two-dimensional and three-dimensional micro-dust systems. Also, approaches to determine the dust size (distribution) and dust density (distribution) in a nano-dust cloud are presented.
