| Abstract: | Laser light scattering is the most advanced and reliable method for measuring both the static and dynamic properties of liquid crystals. Many parameters such as molecular weight, optical turbidity, correlation length, phase transition temperature, splay pitch and twist can be measured by this technique. These parameters are very significant in the theoretical analysis of liquid crystals and their applications in optoelectronics. |
