Abstract
We shall describe our on-going work on the study of the impact of light scattering by liquid crystals on the image quality. We shall start by the analyses of the case of a uniform nematic film. Then, a particular attention will be paid to the case of using electrically tunable liquid crystal lenses for mobile cameras. As a result, we shall show that we can quantify this impact and deploy various deconvolution techniques to reduce the impact of scattering. This, in turn, will eliminate one of the key drawbacks when using liquid crystals for adaptive imaging.
