Paper Abstract

Beam colouring effects traversing a different light-scattering medium based on liquid crystals experimental investigations are presented. It was first time shown that the result of the beam colouring at the medium output depends on the singly forward scattered partial signals phase delays magnitudes. Colouring effects spectral investigation has been carried out using both nematic liquid crystals with carbon nanotubes and the solution of liquid crystal in a polymer matrix which was previously investigated. The non-scattered and the singly forward scattered interfering components amplitude ratio significantly affects the colour intensity in both samples. It has further been established that the spectral content of the illuminating beam strongly influences the colour of the resulting radiation. The colouring effect significant increase has been achieved due to the injection of carbon nanotubes, as well as the sensitivity of the liquid crystal to the control electric field has increased.
