Abstract

Experiments with different types of near-field microscopes have demonstrated that the classical diffraction limit of conventional optical systems can be beaten. In these experiments, the resolution of the images is determined, primarily, by the size of the probe. One of these techniques consists of using scatterers in the near field of the sample. High resolutions have been demonstrated with this kind of scheme, although the signals are weak and the image formation is rather complex. Systematic studies are required to understand the properties and capabilities of the technique. Efforts are being made by many groups to understand the relation between the probe, the object and the image. In this work we present an experimental study of the image formation properties of different types of scatter-probe near-field optical microscopes.
