摘要
分析计算了X光束的相干性对X光全息图分辨率的影响.结论是,X光无透镜傅里叶交换全息术所要求的相干长度和分辨率与样品尺寸成二次线型关系；X同轴全息术所要求的相干长度和分辨率的平方以及样品到全息图的距离成正比.
Abstract
The effectS of the coherence of X-ray beams on the resolution of X-ray holograms are theoretically analyzed. The concluSion is that the temporal coherence length required for X-ray beams is a quadratic function of the resolution and the size of specimen in X-ray lensless Fourier transform holographyj and the temporal length required for X-ray beams is proportional to the square of the resolution in X-ray in line holography.
