A Grating-Aligned Ferroelectric Liquid Crystal Electro-Optic Shutter for Fast-Switching and Shock-Resistant Applications

摘要

Sub-millisecond electro-optic switching times of ferroelectric liquid crystals (FLCs) remain highly desirable for fast switching devices, such as LCoS display applications. Such materials are notoriously susceptible to damage through shock-induced flow. A simple shock-stable geometry for FLC electro-optic shutters is presented, based on homeotropic surface-relief gratings.
