Abstract

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