Demonstration Set-Up for Fast Switchable Diffraction of Laser Light Using the Computer Controlled Diffraction Grating Based on Ferroelectric Liquid Crystal

Abstract

ABSTRACTSwitchable 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.
