Fourier Transform Holography - Single Shot Imaging on a Photon Budget
||Capturing single-shot images on the nanoscale at LCLS will require
techniques that are compatible with coherent, ultrafast, high-
intensity x-ray pulses. Fourier transform holography (FTH) is one
The key to realizing FTH at soft X-ray wavelengths is the integration
of a nanoscale transmission mask with the sample. The mask, which
defines the holographic object and reference beams, is fabricated by
focused ion beam milling.
Building upon these single-shot compatible principles, we have
developed methods to extend the field of view, increase the signal-
to-noise ratio, and a scheme for pump-probe imaging.
First proof-of-principle experiments have been performed on 3rd
generation storage ring sources.
