Abstract
A Fresnel lens with electrically-tunable diffraction efficiency while possessing high image quality is demonstrated using a phase-separated composite film (PSCOF). The light scattering-free PSCOF is obtained by anisotropic phase separation between liquid crystal and polymer. Such a lens can be operated below 12 volts and its switching time is reasonably fast (similar to 10 ms). The maximum diffraction efficiency reaches similar to 35% for a linearly polarized light, which is close to the theoretical limit of 41%.
