Complex plasmas are low temperature plasmas containing microparticles in addition to the ions, electrons and neutral particles. Under most laboratory conditions, the microparticles are charged negatively by collecting electrons from the plasma. They then interact with each other via a screened Coulomb potential, forming, for instance, a crystalline phase [1]. When the microparticles are illuminated with a laser sheet, their positions can be recorded with a conventional camera. This allows
