The high brilliance of an accelerator-based coherent source is employed for scanning near-field microscopy in the THz and sub-THz range. Spatial resolution below the diffraction limit is achieved. Different approaches for the near-field probe are discussed. Together with a Martin-Puplett spectrometer this technique enables spectroscopic mapping. The potential of the technique is exemplified by imaging biological samples.
