Abstract
We modified the measurement and evaluation scheme developed for the dispersion analysis of triclinic crystals to perform dispersion analysis of arbitrarily cut uniaxial crystals. In addition to the dispersion parameters, we determine the orientation of the optical axis and can distinguish between degenerate and non-degenerate vibrational modes. The investigated crystals comprise quartz, calcite and lithium niobate, which exhibit different levels of difficulty to evaluate the dispersion parameters and the correct orientation.
