Abstract.   Variation of observation scheme is shown to lead to the transformation of crystal conoscopic figures thus expanding the method capabilities in investigation of optically active crystals. Results of experiments carried out with TeO2 active crystal under changes in position of a quarter-wave plate in the optical observation system are presented.
Keywords: interference, circular polarization, conoscopic pattern, quarter-wave phase plate
