Reflective Method for Determining the Orientation of the Optical Axis of Uniaxial Crystals and Stressed Materials

This paper considers a method for determining the orientation of the optical axis of a uniaxial crystal by the value of the reflection coefficients difference of the orthogonally linearly polarized light waves. On the example of optical calcite, the applicability of the method for determining the orientation of the optical axis is shown. The results of the determination the orientation of the optical axis of crystal NBT in the proposed reflective method are described
