Improvement of the resolution on the basis of use of spatial filters

Abstract

Researches on resolution improvement at use of a spatial filtration are given. Spatial filters such as Toraldo, the vortex phase plate, the shadow filter are used. Also for reduction of a spot of confusion it is used conical axicon. Results of experiments are given at use of the above-named filters. Efficiency of a spatial filtration for resolution improvement is shown.
