Abstract
The expression for the spectral power density of the static spatial optical noise (Wiener spectrum) in the light transmitted by a thin film of polymer-encapsulated ferroelectric liquid crystals is derived. Monodisperse half-spherical droplets of a bistable ferroelectric liquid crystal with a homogeneous planar orientation of directors are considered. Within the framework of the model of nonoverlapping disks, an analysis is performed concerning the influence of spatial correlation of the droplet positions on the shape of the noise spectrum and the signal-to-noise ratio during the realignment of the droplet director in an external electric field. The influence of misalignment of the droplet axes on the level of the static spatial optical noise is studied.
