The spatial resolution of most of the imaging or microcharacterization methods presently in use are fundamentally limited by the wavelength of the exciting or the emitted radiation being used. In general, the smaller the wavelength of the exciting probe, the greater the structural damage to the sample under study. Thus, the requirements of minimal sample alteration and high spatial resolution seem to be at odds with one another.However, the reason for this wavelength resolution limit is due to the far field methods for producing or detecting the radiation of interest. If one does not use far field optics, but rather the method of near field imaging, the spatial resolution attainable can be much smaller than the wavelength of the radiation used. This method of near field imaging has a general applicability for all wave probes.

Six years ago there was a symposium held at the 1991 EMS A meeting to discuss the issue of “Resolution in the Microscope”.1 In this paper, we will look at resolution in near-field imaging, a blossoming field, and see whether any of our concepts have changed.It has been only within the last decade that the concept of super-resolution microscopy in the near field has been vigorously pursued and experimentally demonstrated. (For reviews on the subject, the reader is referred to the proceedings of the second and third international conferences on near field optics.) However, as in most areas of microscopy, the idea is not new, but rather rediscovered after decades of dormancy.The idea of optical resolution unhindered by far-field diffraction limitations was conceived more than a half-century ago by E.H. Synge4 in a paper entitled “A Suggested Method for Extending Microscopy Resolution into the Ultra-Microscope Regime”.
