Abstract

When a coherent beam propagates through a strong scattering medium, a speckle pattern of the output field can be formed due to random scattering. As a consequence, it is impossible to directly acquire the original information of the input beam from the output scattering field. However, in the random scattering process, the output speckle pattern still contains the original information of the incident beam. The acquirement of the original information based on speckle patterns for the reconstruction of an object has become a hot research topic. As for this problem, the techniques including speckle correlation, transmission matrix, wavefront control as well as time reversal and phase conjugation have been proposed. The scattering imaging technique based on correlation holographic theory is mainly introduced, in which its principle, history and recent new progress are included. In addition, its future development is prospected.
