A novel practical configuration for superresolution is presented,which relies on the polar reversal property of some irradiance redistribution elements and the profile of TEM00 mode Gaussian laser beam.Gaussian peak of incident light coming into the central part of such element,may go out from near the peripheral part of element,and the skirt of Gaussian beam coming into peripheral part goes out from central part.Thus,the optical superresolution is obtained in an imaging system.Compared with the filter,the energy loss is greatly diminished and the deserted light energy is recovered.
