Optical methods for measuring the interaction potential between macroparticles in a gas discharge plasma

A new method for determining interaction forces between particles in non-ideal dissipative systems with isotropic pair potentials is presented. The method is based on solving the inverse problem which describes motion of particles by a system of Langevin equations, and also allows us to restore the parameters of external confining potential. Also, a new method of image recognition of dust particles is proposed.
