台式X射线同轴全息重现中干扰衍射斑的消除
Elimination of Disturbing Diffraction in Reconstruction of Table-topX-ray In-line Holography
摘要
针对X射线全息实验中光源的特点,探讨了用参考光的共轭光束重现时像面上将出现的0级和+1级的衍射光斑的成因,在部分相干光照明情况下数字重现时分别提出了解决方法.归纳了不同光路尺度下全息重现的一般规律,并提出某些情况下可能用到的其他几种改善重现像的途径.
Abstract
By studying an imaginary table top in line X ray holography experiment, the article explained the causation of 0 and +1 rank diffraction stripes on reconstructed plane and presents solutions for both problems. Some common principles of reconstruction and some other methods for improving the resolution are also discussed.
