In present paper reference beam and shear dual-hologram methods conjointly using only Mach-Zehnder holograms made more successful measuring characteristic densities, density gradients and studying a jet structure: weak shocks following by expansion waves. The effect of fast transition to a transonic regime accompanying the disintegration of a jet was observed and densities in transition region were evaluated. As a whole, method of dual-hologram interferometry has showed their self-descriptiveness, flexibility and utility for optical diagnostics of a weak gas dynamic micro object - the supersonic air micro jet. Finally, experimental data obtained from the both techniques were numerically compared.
