Transverse shift of helical beams and subdiffraction imaging

An imaging technique is here proposed to overcome the classical "diffraction limit" by using helical beams. This technique and the analysis presented are valid for all kinds of waves (either optical or acoustical) as long as the field can be considered as scalar. We show that the stable st...
