  We study the effects of droplet ordering in initial optical transmittance
through polymer dispersed liquid crystal (PDLC) films prepared in the presence
of an electrical field. The experimental data are interpreted by using a
theoretical approach to light scattering in PDLC films that explicitly relates
optical transmittance and the order parameters characterizing both the
orientational structures inside bipolar droplets and orientational distribution
of the droplets. The theory relies on the Rayleigh-Gans approximation and uses
the Percus-Yevick approximation to take into account the effects due to droplet
positional correlations.
