Paper Abstract

A simple and flexible method is presented for constructing a dark spherical spot array with the prescribed spot number and interval along the optical axis. Through reversing the field radiated from a uniform magnetic current line source in combination with an electric current line source having a cosine-squared taper, the desired focal field can be realized in the 4Pi focusing system. The required incident field on the pupil plane can be obtained by solving the inverse problem and is found to be an amplitude-modulated radially polarized beam.
