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.

The advances in 3D data modelling methods are becoming increasingly popular in the areas of biology, chemistry and medical applications. The Nuclear Magnetic Resonance Imaging (NMRI) technique has progressed at a spectacular rate over the past few years, its uses have been spread over many applications throughout the body in both anatomical and functional investigations. In this paper we present the application of Zernike polynomials for 3D mesh model of the head using the contour acquired of cross-sectional slices by active contour model extraction and we propose the visualization with OpenGL 3D Graphics of the 2D-3D (slice-surface) information for the diagnostic aid in medical applications.
