**7. Conclusion**

From the results described above it can be concluded that the holography based on the Weigert's effect has the following advantages:

7.1 Holographic recording and reconstruction of the polarization in some particular cases.

7.2 Holographic recording and reconstruction of statistical polarization structure of unpolarized light.

7.3 The possibility of creation of the holographic diffractive optical elements with anisotropic structure with advanced features.

7.4 Some new processes (for example selfrecording) in the investigation of dynamic processes of holographic recording based on the Weigert's effect.

7.5 Some new approaches in investigation of mechanisms of Weigert's effect in the Azodyes.
