Annotation: In this work we investigated the diffraction efficiency of holographic structures formed in polymer-dispersed liquid crystals and its dependence on temperature and polarity of the reading light. Liquid crystal’s concentration in investigated samples was 25 and 30% wt. We have shown the anisotropy of optical properties and the ability to control the diffraction efficiency by heating the sample. Diffraction structures was formed by He-Ne laser with wavelength 633 nm.
