Liquid-Crystal Spatial Light Modulators and Their Applications
摘要
Liquid-crystal spatial light modulators control the optical path of light waves by modulating the refractive index. They play an important role in adaptive optics as phase-correction devices. This chapter expounds on the domestic and foreign development and research status of liquid-crystal spatial light modulators and light-beam modulation. The principles of optical-amplitude and phase modulation of liquid-crystal spatial light modulators are introduced, and their future applications are proposed.
