Abstract
A method is developed which is successful in exploiting binary image writing. By exploiting the high sensitivity of a medium, permanent recording are achieved by using a single pulse of the second harmonic of a Nd:YAG laser. The dye-doped liquid crystals are demonstrated to possess very interesting storage capabilities: no image degradation after more than one year, high spatial resolution, high sensitivity, and polarization sensitivity.File in questo prodotto:
