Paper Abstract

We have developed a Photo Addressed Liquid Crystal Light Valve (PALV) that incorporates Smectic C* liquid crystal and a photoconductor and a precise addressing method with laser scanning. The PALV system acts as a secondary imaging plate for imaging and printing. Fast writing speed of 2 sec and resolution of 10 lp/mm were achieved experimentally. The resolution mainly depends on driving frequency and alignment of Smectic C*. The PALV has the possibility of higher resolution in the future. 1.
