Exploration of liquid crystal structures using fluorescent confocal polarizing microscopy

We employed fluorescence confocal polarizing microscopy (FCPM) to visualize three-dimensional patterns of the director field in cholesteric and nematic liquid crystals (LCs). Two types of textures were investigated: fingerprint and schlieren, by both FCPM imaging and conventional polarizing optical...

Description
Summary:We employed fluorescence confocal polarizing microscopy (FCPM) to visualize three-dimensional patterns of the director field in cholesteric and nematic liquid crystals (LCs). Two types of textures were investigated: fingerprint and schlieren, by both FCPM imaging and conventional polarizing optical microscopy (POM). Some kinds of spontaneous periodic distribution of the nematic director were presented.
