A new reconstruction method based on classical molecular dynamics of neutron penumbral imaging in ICF

In the past, the study of neutron penumbral imaging technique often relied on linear reconstruction methods. Due to the linear approximation, the linear methods often caused the aberration in reconstruction results. Furthermore, because the smooth neutron background that influences the linear reconstruction result is difficult to estimate and remove, the linear reconstruction methods cannot work well either. In this paper, we propose a new nonlinear method based on classical molecular dynamics to improve the results. This paper discusses the principle of the new method and presents some of the reconstruction results, which are then compared with the results of Wiener method, one of the linear methods.
