Supplementary Codes contain four codes: PSFofBesselBeam_Axicon.m, maskDesign.m, demo1.m, and demo2.m. The code “maskDesign.m” generates four masks with the inner and the outer diameters located at 1/e, 1/(5e), 1/(10e) and 1/(15e) of the peak amplitude of the ring, respectively. The transmittance ratios of these four masks under ideal conditions are 92.4%, 99.0%, 99.6% and 99.8%, respectively. The code “PSFofBesselBeam_Axicon.m” simulate the electrical fields at the mask plane and at the back focal plane of the objective,...
