DEFECTS AND TEXTURES IN CHOLESTERIC ANALOGUES GIVEN BY SOME BIOLOGICAL SYSTEMS

This paper presents the diffraction properties of cholesterics with a pitch gradient and is based on a work on the optical properties of perfect cholesteric liquid crystals

In conclusion we can state that locally Cl symmetric cholesteric structures (or locally C2 symmetric ones with the symmetry axis parallel to the helical axis) supporting a

Experiments were performed both in wedge-shaped cells using liquid crystals with a positive or negative dielectric anisotropy and in a parallel cell using a liquid
