X射线同轴全息术中像差的数字模拟

Simulation to Aberrations in In-Line X-ray Holography

给出了Ｘ射线同轴全息中像差的数值模拟．分别研究了其三级波差和光线像差，用一个较为简便的方法计算出光线像差，给出了类似于光线追迹中的点列图，并由此相应地估计出像差对分辨率的限制．所有的计算都是基于一个典型的Ｘ射线激光全息实验中的参数进行的．根据分析还讨论了减小像差的条件．

A digital simulation to aberrations in in-line X-ray holography, and the third order wave aberration and ray aberration are discussed. The ray aberration is derived via a relatively simple method. The point diagrams are gives and the resolution limiting is estimated based on a typical holography with x-ray laser. Some propositions for reducing aberrations are given.
