Paper Abstract

Theoretically, it is well known that the classical optical microscope resolution, is limited to about 250 nm. Actually, the scanning near-field optical microscopy allow to get over this limit. Using a vibrating opaque metallic tip, which periodically and locally perturbs the electromagnetic field distribution of a focused laser spot in to the sample surface, we have observed with better resolution than the theoretical limit many topographic and optical test object.
