Multiple light scattering in nematic liquid crystals

Abstract

We present a rigorous treatment of the diffusion approximation for multiple light scattering in anisotropic random media, and apply it to director fluctuations in a nematic liquid crystal. For a typical nematic material, 5CB, we give numerical values of the diffusion constants $D_{\Vert }$ and $D_{\perp }$. We also calculate the temporal autocorrelation function measured in Diffusing Wave Spectroscopy.
