Abstract- By combining circular and linear structure of Fresnel zone plate a novel diffractive element is created which is able to generate double focal points. The presented element is theoretically studied and its focusing behavior is demonstrated by simulation. We illustrated that the generated double focal points are easily manipulated. Besides, some experiments arranged to verify the simulation results.
