Within the framework of the single scattering and the anomalous diffraction approach, the conditions for coherent transmittance quenching for surface ferroelectric liquid crystal (SFLC) droplets have been found. The influence of the droplet polydispersity and the disorientation of their optical axes for the SFLC film for the conditions under which the film coherent transmittance becomes zero is analysed. The contrast ratio and the modulation depth of the SFLC film under the conditions of coherent transmission quenching have been studied. The possibility of a dramatic increase in the contrast ratio at fields of view of a few degrees is shown. Analysis of the contrast ratio and modulation depth of the SFLC film under the conditions of coherent component quenching and at a departure from these conditions has been performed.

Light scattering by a monolayer of bipolar nematic droplets encapsulated in polymer film is examined both experimentally and theoretically. A method for the simulation of the angular distribution of scattered light is based on the anomalous diffraction and interference approximations taking into account the director configuration within liquid crystal droplets and their bipolar axes orientation. The director configuration in nematic droplets is calculated using the relaxation method of the free energy minimization. The characteristics of the sample, including distribution of droplet sizes and shape anisometry, are measured in details. The experimental results and theoretical data agree closely with each other.
