“…There is no theoretical reason why submicron resolution should not be attainable by using our method, and we predict this development. Experience with in-line holography, in particular photoelectron and LEED holography, indicates that improved z-axis resolution can be obtained by combining holograms at different wavelengths (29)(30)(31)(32)(33), an option now practical for DIH through the ready availability of cheap green, blue, and UV lasers.…”

Digital in-line holography with numerical reconstruction has been developed into a new tool, specifically for biological applications, that routinely achieves both lateral and depth resolution, at least at the micron level, in three-dimensional imaging. The experimental and numerical procedures have been incorporated into a program package with a very fast reconstruction algorithm that is now capable of real-time reconstruction. This capability is demonstrated for diverse objects, such as suspension of microspheres and biological samples (diatom, the head of Drosophila melanogaster), and the advantages are discussed by comparing holographic reconstructions with images taken by using conventional compound light microscopy.

Complex X-ray holography (CXH) using resonant scattering is proposed as a new atomic resolution holography method. CXH provides us a solution for the twin-image problem as well as elemental identification in real space. Accurate differences among intensities recorded at several X-ray energies around an absorption edge must be experimentally obtained in the CXH method. Taking into account that the holographic signal is of the order of 0.1% of its background, we find it difficult to carry out using ordinary technique for hologram measurement. Thus, in order to measure holograms with a very good S/N ratio, a sample was cooled about 100 K and fluorescent X-rays were focused on a detector with a cylindrical graphite analyzer in the X-ray fluorescence holography apparatus at SPring-8. Ga fluorescent holograms of GaAs were recorded at energies near the As K absorption edge. A change of holographic oscillations due to the resonant scattering, which is expected from the computer simulation, was firstly observed. q
