We fabricated the liquid crystal cell which had the property of the diffraction optical element. The concentric electrode had been fabricated on an indium-tin-oxide (ITO) substrate by etching technology. With the application of a proper voltage, it produces an inhomogeneous grating-like electric field in space to form phase Fresnel liquid crystal lens.
Because of liquid crystals (LCs) are excellent electro-optic materials with electrical and optical anisotropies. Their optical properties can easily be modulated by the external electric field. Hence based on the electro-optic properties, the function of the as-constructed phase Fresnel liquid crystal lens has been studied in this paper.
In this study, we discuss the diffraction efficiency of Fresnel LC lenses and collocated plano-convex to form dual focal length optical element.
