Abstract
This paper presents the two methods enabling to determine distributions of electron density and/or electron temperature of the plasma sheath originating in plasma-focus phenomenon. These methods are based on theoretical considerations and processing of experimental results taken by means of high-speed frame photography in narrow band of visible spectrum and multi-frame laser interferometry. Both high-speed photography subsystems can operate simultaneously with sub nanosecond accuracy and allow recording frame sequence of plasma with temporal resolution of about 1 ns and spatial resolution of about 0.1 mm. They are also equipped with digital readout. The detailed explanations and considerations concerning presented methods are exemplified by results obtained in experimental investigations.
