2. Liquid crystals and spatial light modulators

2.1 Thermotropic nematic liquid crystals

Liquid crystals (LCs) are mesomorphic materials, composed of elongated organic molecules called mesogens . These are long carbon chains, typically a few nanometers in length, usually represented as rods. The fluid nature of liquid crystals allows various arrangements of their molecules, called mesophases, whose ordering properties are intermediate between those of crystals and liquids, and...
