We propose the analysis of 2D intensity contour maps which is based on the optical transmission function for the polarizer-specimen-analyzer system. A small modification of the high-accuracy universal polarimeter (HAUP) technique was used to measure the intensity maps (HAUP maps) and determine the phase retardation, linear dichroism (LD) parameters, and multiple light reflection contribution in uniaxial crystals. We have performed measurements in a direction perpendicular to the optical axis on pure birefringent LiNbO3, birefringent optically active SiO2, and two birefringent optically active dichroic galogermanate crystals doped with Mn3+ and Cr3+ ions. We have obtained good agreement of the experimental data for 532, 633, and 650 nm wavelengths with analytical values. These results extend the capabilities of high-accuracy polarimetry to anisotropic crystal studies.
