Paper Abstract

An electrically controllable radial birefringent pupil filter is proposed in this paper. It consists of two polarizers and an improved electrically controllable optical azimuth rotator which has two λ/4 retarders, one electro-optical element and one radial birefringent crystal. Evolution and distribution of polarization states of this pupil filter is discussed. The most interesting and useful advantage of such a structure is that characteristic of intensity distribution near focus can be obtained merely controlling the applied-voltage for optimal electrical inductive phase difference Γ of the electro-optical element and azimuth angle of radial birefringent crystal. And the Γ zones are given where transverse superresolution and extended focal depth or focal shift can simultaneously be obtained.
