Paper Abstract

Liquid crystal films that scatter light as a function of voltage are used as the active parts of optical switches and attenuators. The optical properties of the film are studied here and the distribution and efficiency of the scattering are counted. How light bends in a droplet is calculated using geometric optics, which can also be used to estimate the efficiency of scattering.
