Three Dimensional Imaging of ICF Targets |

Abstract: | A CT technique applied to ICF is developed and a three dimensional (3D) image reconstruction propram (CT3D) is performed. The 3D images of target′s plasma are reconstructed by using a multiplicatic algebraic reconstruction technique (MART) from five pinhole camera images obatined along different sight directions. The technique has been used to measure the three dimensional distribution of X ray of laser plasma experiments in the “Xingguang Ⅱ” facility, and the good results are obtained. It show that the CT technique can be applied to ICF experiments. |
