M. Totzeck et Ma. Krumbugel, LATERAL RESOLUTION IN THE NEAR-FIELD AND FAR-FIELD PHASE IMAGES OF PI-PHASESHIFTING STRUCTURES, Optics communications, 112(3-4), 1994, pp. 189-200
The resolution in the phase distribution of coherent images of strong
phase objects is investigated using moment method near field calculati
ons and simulated far field images. It is demonstrated that an apparen
t superresolution for pi-phaseshifts corresponds to a threshold criter
ion and that the images depend strongly on polarization and refractive
index.
