Abstract
Two optical methods were applied to obtain information about the director configuration in electrically induced convective instabilities. The intensity of the transmitted light and the contrast of the patterns were measured. Normal, oblique and ‘abnormal’ rolls were studied and compared for initially planar and homeotropic samples.Keywords
