Liquid-Crystal Light-Control Experiments

  • R. A. Soref
Conference paper


Liquid crystals are sensitive to a number of external influences: Pressure, temperature, mechanical shear, low-frequency electric fields, low-frequency magnetic fields, ultraviolet irradiation, and chemical vapors. Any of these stimuli can produce a measurable change in the liquid crystal’s light-scattering properties. Light “control” is possible because the external stimuli modify the optical scattering pattern. They control the amplitude, phase, and angular direction of light emerging from the liquid crystal.
