Abstract

We present what we believe to be the first implementation of Fourier transform (FT) holography using a tabletop coherent x-ray source. By applying curvature correction to compensate for the large angles inherent in high-NA coherent imaging, we achieve image resolution of 89 nm using high-harmonic beams at a wavelength of 29 nm . Moreover, by combining holography with iterative phase retrieval, we improve the image resolution to < 53 nm . We also demonstrate that FT holography can be used effectively with short exposure times of 30 s . This technique will enable biological and materials microscopy with simultaneously high spatial and temporal resolution on a tabletop soft-x-ray source.
