    The optical intensity distribution in the focal volume plays an important role on the performance for many optical systems. Effective manipulation of focused optical intensity distribution can be obtained by using a pupil filter composed by zonal optical diffractive element and zonal double half-wave plate which can modulate both the phase and the direction of polarization of incident radially polarized beam zone by zone, and turn radially polarized beam into zonal sylindrically polarized beam. Numerical simulations of Matlab show that different intensity distributions can be obtained in the focal volume. Using the method, besides the existing doughnut intensity distribution and flattop focal spot in focal plane, the flattop doughnut intensity in the focal plane with hollow three-dimension (3D) pattern is obtained. This result can find potential use in fields such as particle manipulation and caption, laser micromachining, etc.
