- Abstract
A type of tunable liquid crystal diffractive lens (TLCDL) for monochromatic wave base on multiorder diffraction is proposed and demonstrated. Two TLCDLs were designed using patterned indium tin oxide and a conductive surface relief electrode, respectively. The focus tuning mechanism of the lens has been proved using multiorder diffractive structure. One TLCDL with three switchable focal lengths was fabricated using an imprinting technique, which significantly reduced fabrication complexity. Electro-optic performances of the TLCDL were studied with monochromatic illumination. High image quality with low operating voltage and fast response time has been realized.
