Abstract
The director field of a cholesteric liquid crystal confined to cylindrical cavities with parallel and perpendicular surface anchoring was studied by means of optical polarizing microscopy. The chirality of the liquid crystal could be varied continuously due to a temperature-induced twist inversion of the cholesteric structure. The results indicate the occurrence of a twisted escaped radial structure for perpendicular anchoring and an eccentric double twist configuration for parallel anchoring. © 1996 The American Physical Society.
