Abstract
In this paper we demonstrate the method of widefield amplitude-phase object images reconstruction from the spatially-limited broadband terahertz wavefield spectral components distributions in the Fresnel diffraction zone, based on the wave propagation equations iterative solution algorithm. Using of this method allows one to overpass the spatial resolution limit of an object image, reconstructed from the digital pulse terahertz hologram in low-frequency components of the THz radiation, used in the research. In its turn the created software allows to simulate the process of holograms registration in case of limited detector aperture and to reconstruct the full images of an object.
