DelRe The mixing of propagating and evanescent light waves to form images in the near field of an emitting or reflecting surface is crucial to developing new imaging techniques. The lack of a remote superresolving detection scheme, however, has left this area largely unexplored. In this study, a remote structured-illumination technique is used to inspect imaging in the near field for THz frequencies (wavelengths of 0.1—1 mm). The authors demonstrate a simple mechanical scheme to overcome the diffraction limit, achieving a resolution better than 1/10 of the wavelength, which may allow the development of inexpensive, superresolved THz imagers for e . g . security applications.
