Single{\_}Shot Diffraction Limited Fourier Holography Scheme using a Table top Soft X-ray Laser

POSTER

Abstract

Single-shot Fourier transform holography has been demonstrated utilizing a 46.9~nm table-top plasma discharge laser. A zone plate illuminated by the laser light is used to form both the reference wave and the object waves. The object waves are formed from plane waves scattering off a non-transparent object. The interference pattern between the spherical reference wave and the object waves is recorded on a charge-coupled device. The resolution limit of 150~nm is determined by the focal spot size of the zone plate. A knife-edge scan of the resulting hologram obtains a single-shot spatial resolution of 163~nm. This setup has been designed for analyzing nano-pillar dynamics for the purpose of single-molecule mass detection. The nonlinear coupling between pillars allows for a higher sensitivity than single pillar detection schemes.
