Abstract
We developed a new variant of Fourier transform holography (FTH) to overcome the separation condition of FTH by subtracting the autocorrelation signal, named as autocorrelation-subtracted FTH (AS-FHT). AS-FTH is advantageous in imaging large specimen using light sources of limited coherent photons because AS-FTH requires a much smaller coherent illumination area than conventional FTH. We experimentally demonstrated the AS-FTH using a Ni-like Ag x-ray laser at 13.9 nm. The hidden part of an image under its autocorrelation was successfully recovered by subtracting an independently measured autocorrelation signal.
