分析了Ｘ射线全息记录过程中影响分辨率的一些主要因素。在完全相干的条件下，Ｘ射线无透镜傅里叶变换全息图的最小分辨距离不可能小于记录时用的Ｘ射线聚束器的焦斑或滤波小孔的半径，而Ｘ射线同轴全息图不可能获得比记录介质的截止频率更高的分辨率。在部分相干的条件下，Ｘ射线无透镜傅里叶变换全息所要求的相干长度和分辨率与样品半径成二次线型关系。Ｙ射线同轴全息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，而与样品尺寸无关。随着Ｘ射线全息图分辨率的提高，其所要求的相干长度将大幅度增长。
Some main factors influencing resolution in X-ray holographic recording are analyzed. Under perfectly coherent conditions, the minimum resolving distance of an X-ray lensless Fourier transform hologram can not be less than the focal spot or filtered aperture radius of an X-ray beamformer used for recording, whereas an X-ray coaxial hologram It is impossible to obtain a higher resolution than the cut-off frequency of the recording medium. Under partially coherent conditions, the coherence length and resolution required for x-ray lensless Fourier transform holograms have a quadratic linear relationship with the sample radius. The coherence length and resolution squared required for Y-ray co-axial holography and the distance from the sample to the hologram are proportional to the sample size. As the resolution of X-ray holograms increases, the required coherence length will increase dramatically.
