摘要：

Terahertz (THz) imaging offers many attractive advantages over existing modalities especially in its ability to obtain spectroscopic information. In particular, THz spectra are extremely sensitive to small changes of the molecular structure and different isomeric and intermolecular configurations. With a, comparatively longer wavelength (0.3 min at 1 THz), Rayleigh's criterion limits its use for imaging single cells and other microstructures. A method for breaking the Rayleigh's criterion and thus achieving sub-wavelength resolution is to adopt nearfield imaging techniques. This paper reviews the existing THz near-field methods and recent developments for identifying potential areas of research.
