Electrooptic Liquid Crystal Devices: Principles and Applications

The principles governing the operation and performance of devices utilizing mesomorphic anisotropic fluids (liquid crystals) am reviewed and systematized according to materials, dielectric type, and mode of operation. A further breakdown is made into whether the phenomenon is a change in optical density (color), diffraction, or scattering. Some of the possible directions for optical applications are indicated for which liquid crystals may be unique. Performance, life, circuit parameters, and drive characteristics are considered.
