Abstract ： The focusing properties of fractal zone plates (FZPs) with different structure parameters are studied experimentally. The axial irradiance of FZPs is deduced at n=4. The experimental results are in good agreement with the theoretical prediction. A method to fabricate FZPs with variable structure parameters is mentioned, and the liquid-crystal-on-silicon device is used to implement this experiment. The experimental results indicate that the focal depth of lower order FZPs is larger than that of higher order FZPs.
