Abstract

Switchable diffraction grating with 80 “idependently drived transparent stripe electrodes with spatial resolution 40 l/mm based on ferroelectric liquid crystal is presented. The switching of the diffraction angle till frequency 1kHz is demonstrated using the computer choise of assemblies of electrodes.
