菲涅耳波带片用于X射线源的消色差成像测量
Fresnel zone plates for Achromatic Imaging Survey of X-ray sources
摘要:
在相当长的一段时间里,菲涅耳波带片望远镜一直被认为是X射线和伽马射线的优秀成像掩模。通过适当选择波带片材料、间距和适当的读出系统,可以实现任何理论角分辨率。我们提供了如何大量的X射线源可以在高分辨率成像的数值模拟的结果。我们相信,这样的成像仪将是一个很好的工具,为未来的调查任务的X射线和伽马射线源,我们建议。
英文摘要:
A telescope with Fresnel Zone Plates has been contemplated to be an excellent imaging mask in X-rays and gamma-rays for quite some time. With a proper choice of zone plate material, spacing and an appropriate readout system it is possible to achieve any theoretical angular resolution. We provide the results of numerical simulations of how a large number of X-ray sources could be imaged at a high resolution. We believe that such an imager would be an excellent tool for a future survey mission for X-ray and gamma-ray sources which we propose.
