This chapter discusses some techniques such as the use of superoscillatory filters (SOFs) and the use of resonant scatterers in the near‐field of the imaged objects. It also discusses the techniques in providing quantitative holographic images of the inspected medium. The chapter describes an approach to design a SOFs and discusses the applications of this filter to overcome the diffraction limit of the resolution in holographic imaging. It considers a technique to perform subdiffraction imaging by using scatterers in the proximity of the imaged objects. A technique has been proposed to perform quantitative microwave holographic reconstruction in quasi‐real time. Both the real and the imaginary parts of the permittivity distribution of a dielectric object are recovered quantitatively. A 3D microwave holographic imaging algorithm has been proposed based on the measurement of reflection coefficient. The algorithm offers several modifications for the near‐field 3D holographic imaging originally proposed.
