Abstract: X-ray laser holography is considered to be an important application of X-ray laser.In this papor,the simulation of the record and reconstruction of Gabor hologram is presented,and the influence of image amplification and aberrations for the reconstruction of Gabor hologram and lenseless fourier transform hologram with visible light is discussed,the method to obtain a high resolution amplified reconstruction image with visible light is proposed.The results show that lenseless fourier transform hologram is very important in X-ray laser holography.
