在物平面和全息平面上分别施加限制条件，实现了同轴全息图的位相恢复重现，基本消除了孪生像的干扰。提出了一种软Ｘ射线同轴全息实时成像的方案 In the object plane and the holographic plane were imposed constraints, to achieve the coaxial holographic phase recovery and reproduction, the basic elimination of the twin image interference. A scheme of soft X-ray coaxial holographic real-time imaging is proposed
