Reconstructing X-ray hologram with visible light, without enlargement of it, can sim-plify the process of its reconstrution greatly. For lensless Fourier transform (LLFT) X-ray holography, there is no spherical aberration in it and the spacing of its interference fringes is relatively large. Therefore, it is possible to reconstruct hologram of this type directly with visible light. The effects of aberrations and emulsion shrinkage on the resolution of LLFT X-ray hologram, the conditions for perfect reconstructing of the recorded information are analyzed, and the results of corresponding numerical analyses are also given. As a result, the legibility for direct reconstructing of LLFT X-ray hologram with visible light is verified theoretically, In addition, the longitudinal resolution in X-ray holography is analyzed, and the conditione for longitudinal resolving in X-ray holography are given from the relationship between longitudinal and transverse resolution.
