    • Abstract
  • Millimeter-wave holographic imaging technique is important means for human body security inspection. In order to further improve imaging resolution and image quality, the research of wide-band and high-frequency submillimeter-wave imaging system has great significance. Based on the construction of submillimeter-wave holographic imaging system, this paper proposes an appropriate wide-band holographic reconstruction algorithm. The target image is obtained by the measured phase and amplitude information reconstruction using submillimeter-wave holographic imaging system. Experimental results show that, the wide-band holographic reconstruction algorithm can efficiently reconstruct image within sub-millimeter wave band, to validate the use of wide-band imaging can effectively improve image resolution and suppress speckle effect.
