Generation of spontaneous magnetic fields (SMFs) is one of the most interesting phenomena accompanying an intense laser–matter interaction. One method of credible SMFs measurements is based on the magneto-optical Faraday effect, which requires simultaneous measurements of an angle of polarization plane rotation of a probe wave and plasma electron density. Complex interferometry is an innovative approach in SMF measurement, obtaining information on SMF directly from a phase–amplitude analysis of an image called a complex interferogram. This approach has not been employed in laser plasma research until recently, successfully imlemented in SMF measurement at the Prague Asterix Laser System. In this paper, proprietary construction solutions of polaro-interferometers are presented allowing us to obtain information on the electron density and SMFs distributions in an examined plasma. The theoretical foundations of complex-interferometry are presented.
