Paper Abstract

This study proposes a Fresnel lens with multiple focus modes by combining the technology of polymer stabilized liquid crystals (PSLC) with the novel electrode design, which contains the Fresnel zone electrodes and complementary electrodes. The device was fabricated according the methods including the photolithography for the electrode patterns, the LC cell assembly, and the UV exposure for the PLSC curing. Experimental results show that the diffraction effects of the lens can be switched under different operation modes. It can accordingly provide three focal lengths of 25 cm, 32 cm, and 39.5 cm.
