Ferroelectric Liquid Crystal Compound Lens Based on Pancharatnam–Berry Phase
Crystals, 2022 We report a ferroelectric liquid crystal (FLC) compound lens based on the Pancharatnam–Berry (PB) phase. The phase of the FLC compound lens is an integration of polarization grating and a PB lens. Thus, when light passes through an FLC compound lens, the
