Inscribing Holographic Patterns into a Polymer Liquid Crystals
Two-beam interference holographic patterns have been inscribed into a diacrylate mesogen in a liquid crystalline phase. The recorded holographic pattern can be permanently stored by polymerization of the diacrylate mesogen. In the polymer storage medium, the local orientational ordering is determined by the interfering characteristics of the writing holographic pattern. The mesogenic groups in the regions exposed to constructive interference filed are found to orient in a unique direction, whereas a well aligned polymeric plate is not obtained in those regions exposed to destructive interference field.
