Abstract

In the present paper we discuss the imaging qualities of a birefringent lens. The transmittance of such a lens, sandwiched between two polarizers, varies radially. The fact that the nature of this radial variation of transmittance can be controlled by changing the orientations of the two polarizers relative to the optic axis of the birefringent lens, may be utilised for continuously modifying the imaging characteristics of the lens. The study of the point spread functions (PSF) of such a polarizer-birefringent lens-polarizer combination reveals that this can be utilised both for achieving apodisation and superresolntion.
