We present a liquid crystal (LC) iris based on self-assembled polymer microstructures, utilizing a vertically aligned twisted LC cell with a radial gradient in pretilt angles, positioned between crossed polarizers. This configuration enables electrically tunable aperture control with low operating voltage and high aperture tuning ratio, and simplified fabrication.
