| Abstract: | The decision of the direct and reverse problems in the optics of the low symmetry absorbing crystals are obtained and graphically represented by the specific drawing on the Poincare sphere. The direct problem is connected with the transmission and reflection of the normally incident light wave and reverse problem — with the determination of the own waves parameters. Instead of the usually used boundary conditions the equations of Fresnel and Airy are applied to each of the own waves separately, as the incident, reflected and transmitted waves are represented by the vector sum of the own waves. On the basis of the comparatively simple decision of the direct problem the simpliest method of the reverse problem decision, i.e. for the determination of the own waves parameters in the crystal plate is proposed. In the capacity of the experimental data for this purpose the measured polarization parameters, the reflection- and transmission coefficients of the reflected and transmitted waves must be used as well as the right and left circular polarized incident waves and also two different, but close thicknesses of the crystal plate. |
