Online Thickness Gaging of Hot Sheet Steel

该提案是针对第二阶段的SBIR。研究的主要目的是开发一种层析成像仪，能够在热轧钢板制造过程中对其进行全面的在线测量。第一阶段的研究调查了这一概念的可行性，并取得了圆满成功。第二阶段的研究将开发和演示一个原型钢板扫描仪。将优化x射线源和探测器技术，并确定适合进行精确、高速、有限角度断层扫描测量的候选算法。还将开发一系列钢板模型，足以对组件进行详尽的性能评估。该研究对薄板制造技术具有重要意义。

This proposal is for a Phase II SBIR. The primary objective of the research is to develop a tomography gauge capable of making comprehensive, on-line measurements of hot-rolled sheet steel as it is being manufactured. Phase I research investigated the feasibility of this concept and was fully successful. The Phase II research will develop and demonstrate a prototype sheet steel scanner. X-ray source and detector technology will be optimized and candidate algorithms suitable for making precise, high-speed, limited- angle tomography measurements will be defined. A series of sheet steel phantoms, sufficient for exhaustive performance evaluation of the components will also be developed. This research could make a significant contribution to the technology of sheet steel manufacture.
