A new double differential refractometer for student laboratories, based on holographic interferometry in real time with reference hologram and reference fringes, is presented. By studying the interferograms one gets a graphical record of the radial, axial, and temporal distribution of the refraction index in cylindrical tubes. This method permits the determination of the experimental parameters for cases when the relationship between these parameters and the refraction index is known. The paper presents experimental results for gas-discharge parameters.
