• Abstract: The research of scattering imaging is of great significance to the development of various fields, but the existing scattering imaging methods are difficult to combine the advantages of non-invasive, real-time and high quality. In this paper, a new scattering imaging technique is proposed which optimize the traditional autocorrelation imaging technique by multi-stage complexity guidance and the initial acceleration module. We introduce the complexity difference index into the phase iterative recovery step for effective complexity guidance, and add the initial module based on ER iteration to realize fast startup. A series of experiments are carried out to test the performance of the new technique. The results show that the proposed technique significantly improves the scattering reconstruction speed. Meanwhile, the accuracy and clarity of the reconstructed image are significantly higher than the traditional method in terms of fast imaging. Moreover, this technique has better robustness to noise compared to the traditional autocorrelation imaging technique.
