Optical article for reflection modulation

摘要: OPTICAL ARTICLE FOR REFLECTION MODULATION Abstract of the Disclosure An optical article capable modulating reflection polarized monochromatic electromagnetic radiation is disclosed comprised a reflective metal layer, means acting as support for directing to an electrooptic medium that exhibits refractive index which function applied electrical potential, and counter electrode. At least one layer electrode taking form laterally spaced segments. The has thickness less than 0.5 µm, dielectric having in range from 0.1 10 times wavelength at oxide, fluoride, or low molecular weight aromatic compound coated on support. polymeric exhibiting second order polarization susceptibility greater 10-9 electrostatic units polar aligned dipoles electron donor moiety linked through conjugated .pi. bonding system acceptor moiety. differs by 20 percent absence potential.
