(a) Photograph of the conoscopic patterns for the system of two TeO2 crystal plates arranged at an angle of 15° to each other. (b) Dependence of phase difference between ordinary and extraordinary rays on the incidence angle: (1) normally oriented TeO2 plate 7 mm thick; (2) TeO2 plate 7 mm thick arranged at an angle of 15° to the axis of the system; (3) two TeO2 plates with an angle of 15° between them. |
