Foldable and electrically switchable polymer dispersed liquid crystal materials for holographic recording

This paper presented an electrically tunable holographic material fabricated with polymer dispersed liquid crystals for 532nm laser light recording. And we use the polymethylmethacrylate instead of glass substrate to fabricate the liquid crystal films which can be bended. We study the diffraction efficiency of the material and demonstrate the image diffraction of the recorded hologram before and after folding the recording film.
