Laser Light Scattering Study on the Electrohydrodynamic Instability of Nematic Liquid Crystal

抄録

The electrohydrodynamic instability in nematic liquid crystal is investigated by laser light scattering method. The power spectrum of a scattered intensity of light from the liquid crystal cell under ac field is analysed. The forced director fluctuation is observed above a threshold voltage. It is clarified that the director fluctuation is influenced by an onset and a development of the convective flow.
