中子半影成像技术已在劳伦斯利弗莫尔国家实验室得到演示，并已在CEA（法国）用于惯性约束聚变堆芯成像。半影图像中所包含的信息被光圈和相机降级。此外，获得源的估计需要一些特殊的数值重建技术。实现国家点火装置/LMJ项目所需的几μm空间分辨率的主要步骤之一是仔细分析有关降解过程的所有信息。SIRINC的第一个原型版本。将讨论退化模型。将特别注意对重建技术的改进。
Neutron penumbral imaging technique has been demonstrated at the Lawrence Livermore National Laboratory and has been used at CEA (France) to image inertial confinement fusion cores. The information contained in a penumbral image is degraded by the aperture and the camera. In addition, getting an estimate of the source requires some special numerical reconstruction techniques. One of the major steps to achieving a few μm spatial resolution required on the National Ignition Facility/LMJ project is careful analysis of all the information regarding the degradation processes. The first prototype version of SIRINC is presented. The degradation models will be discussed. Particular attention will be given to refinements to the reconstruction technique.
