Abstract

A main goal of use of coherent x-ray beams at 4m generation sources is to achieve an ultimate nm-resolution in x-ray 2D, 3D and even 4D imaging. In conventional full-field x-ray microscopy schemes, the spatial resolution is limited by Airy disc size given by the famous Abbe equation A = 0.61 11 N.A. where NA. is numerical aperture of objective. In visible light microscopy, perfect lenses with numerical apertures of about ~1 are easily available, so it is usually said that the spatial resolution of visible light microscopy is limited by wavelength only. However, the latter is not the case for x-ray full-field microscopy, where angstrom-scale wavelength is nearly completely compensated by extremely poor numerical aperture of existing x-ray imaging optics (for example, Be CRL for hard x-ray focusing with 500-mm focal length has an effective aperture less than 0.5 mm, so that N.A. is below 0.001).
