- W2376060611 abstract "摘要 用光路追踪程序对具有一定尺度的光源通过变栅距凹面光栅后的成像情况进行了研究.证明了对于非点光源，在特定的实验安排下，其焦面仍可以在一个平面内，同时给出了对于不同入射距离的非点光源形成平焦面的波长范围.结果还表明，当光源尺度与入射距离之比小于1∶1000时，光源尺度的变化对焦面位置没有实质性的影响. Abstract Using a ray-tracing code,the imaging process of non-point light sources through a concave grating has been studied.It is demonstrated that under specially designed conditions,a plane spectrum can be formed for non-point light sources.The positions for the plane spectrum have been derived for the sources at different distance from the grating.A criterion has been defined under which the effects of variation of the source-size on the focal plane can be neglected. 作者及机构信息 李英骏2, 杨建伦1, 张 杰2 (1)中国工程物理研究院核物理与化学研究所，成都 610003; (2)中国科学院物理研究所，北京 100080 基金项目: 国家自然科学基金(批准号：1974074)，国家高技术研究发展计划和高温高密度等离子体物理国防科技重点实验室基金(批准号：99JS77.2.1ZK3301)资助的课题.
