  This paper presents the results of studying of dispersed media formation
during the electrical explosion of thin metal wires in vacuum by using
low-current generators ($\sim 1$-$10$~kA). Particular attention is paid to the
analysis of the composition and structure of the corresponding explosion
products as well as to the problem of their visualization using simultaneous
laser interferometry and shadow imaging at two wavelengths (1.064~$\mu$m and
0.532~$\mu$m). Our findings point to the fact that the important role in the
visualization of the explosion products belongs to multiple scattering by
submicron droplets of dense condensed matter, which are mixed with metal vapor.
The hypothesis on the existence of submicron droplets in the products of
exploding metal wires correlates with the results obtained by soft x-ray
radiography combined with a laser probing technique. Taking into account the
multiple scattering by submicron droplets, it is possible to significantly
clarify the parameters of the explosion products visualized via laser probing
techniques as well as to gain a deeper insight into the physics behind the
electrical wire explosion.
