摘要
Contrary to standard wide-field microscopy, the resolution determination of near-field setups is complex, both from the theoretical and the experimental point of view. As a matter of fact, not all the probe and scanning parameters playing a role in the imaging process are exactly known. Moreover, since we are dealing with a scanning probe technique, these parameters can change from one image point to another and lead to different resolving powers of the system. Here we calculate the resolution of transmission near-field optical images by the use of discrete wavelet decomposition. This method allows a local resolution analysis.
