When an electric field is applied across transparent plane-parallel electrodes containing mesomorphic liquids, many complex phenomena occur that depend on the optical, dielectric, and elastic properties of the liquid, the geometry of the test situation, and the nature of the electrical signal/ The electro-optic transfer function is a way of specifying such optical changes. An ever increasing interest in liquid-... 

Fig. 3—Influence of geometrical parameters on scattering electro-optic transfer function measurements. Three cases are illustrated, with their corresponding electro-optic transfer functions (highly schematic).

The electro-optic transfer function at a fixed angle between crossed polarizers is shown in Fig. 5. By swinging between two voltages, it is possible to modulate the color equivalent to a phase retardation at one wavelength (first voltage) to produce a color equivalent to a different wavelength (second voltage). This is the basis for a matrix-... 

Fig. 7—Electro-optic transfer function of twisted structure. Above threshold, increasing the voltage casuses the structure to lose the ability to rotate the plane of polarized light eventually, the optical behavior of the structure approaches that of a perpendicular home-otropic nematic. The difference (e,), however, is still finite at three times threshold. ...

Fig. 13—Photoconductor control of dynamic scattering. Electro-optic transfer function is shown in the dark and under saturated photoconductor conditions. For the liquid crystal to be below threshold voltage in the dark, the value of the applied voltage must not exceed the original threshold voltage plus the voltage drop...

Fig. 9—Electro-optic transfer coefficient along surface orientation for twisted structure. With the source (S) in a plane perpendicular to the electrodes and parallel to the optic axis of the nematic orientation at that electrode, the optical transmission is a monotonic function of angle and voltage (calculated curves). ...
