Applications of X-Ray Holography

Figure 6

Imaging the marine bacteria Cobetia marina in the water window at λ₃ = 2.68 nm using digital in-line holography. (a) SEM image of the used zone plate with a clearly visible central beam stop. (b) Close-up of the zone plate’s outermost zones. (c) X-ray hologram with Cobetia marina in the lower right corner. (d) Reconstruction of hologram (c). (e) Sample Cobetia marina under an optical microscope in bright field illumination (100x, NA = 0.9). (f) Magnified ROI of the reconstructed image as indicated by the rectangle in (d) [33].
