Abstract: (778 Views)
In this paperو checkerboard zone plate is introduced, and its focusing properties are investigated. To this end, three other known zone plates, circular, cross, and square zone plates, are also considered. After that, we compute their point spread functions and compare them together. We demonstrate that the maximum transmitted intensity in the checkerboard is less than that of the circular and higher than either cross and square. Moreover, the width of the checkerboard point spread function transverse intensity is less than that of other considered elements. Finally, the corresponding experiments are considered to verify the simulation results. It is shown that the experimental results are in good agreement with simulation data.
