Abstract
We investigate the possibility of improving the reconstruction accuracy of electron density distributions ne(r) for plasma objects with a complex structure by processing the results of combined interferometry and schlieren photography. We carried out the numerical simulations for a spark channel with a micrometer-sized diameter developing in atmospheric air. We show that the data obtained from the schlieren images significantly refine the results of interferogram processing in the case of plasma objects when the uncertainty in the choice of symmetry of the object or its parts takes place.
