Schematic diagrams of polymer and LC directors orientations of a homeotropic LC gel: (a) , (b) where the LC directors reorientation starts, and (c) where the light scattering takes place.
Voltage-dependent transmittance of the LC gel. . An unpolarized He–Ne laser was used for this measurement.
Voltage-dependent transmittance of the LC gel between parallel and crossed polarizers. Cell gap , , , and .
Measured phase shift of the LC gel at different voltages. and .
