A high-efficiency (97%) and fast polarization converter are achieved using Ferroelectric Liquid Crystal (FLC) by cascading two FLC cells with a 500 contrast ratio. Fast focus modulation is shown without a reverse state. The proposed system is a promising candidate for near-eye-display, such as Virtual Reality /Augmented Reality.
