Abstract :
Nonlinear light scattering phenomena of liquid-crystal films have attracted a lot of research interest since they are useful tools for diagnosing properties of liquid-crystal materials and may have some applications. In the present paper we would like to report and study a new nonlinear light scattering phenomenon from the same planar aligned nematic liquid crystal film structure. This new phenomenon exhibits ring patterns in the orthogonal polarization and is caused by the interference of the scattering lights. The aim of this paper is thus to investigate the influences of the applied electric and optical fields upon these interference patterns both experimentally and theoretically
