Figure 4
Recent results in X-ray ptychography. (a) In situ ptychography on a silk fiber whose response to a change in humidity was investigated. [Reproduced from Esmaeili et al. (2013  ).] (b) First application of ptychography at a free-electron laser. Complex wavefield of a nanofocused X-ray free-electron laser beam. Colors indicate the local phase; amplitude is encoded by brightness. [Reprinted by permission from Macmillan Publishers Ltd: Scientific Reports (Schropp et al., 2013), copyright 2013.] (c) The co-reconstruction of the illumination function allows ptychography to corroborate, for instance, fluorescence microscopy by yielding the input to a deconvolution of the point spread. (i) Amplitude and (ii) phase of the object's transmission. Imaged here is a freshwater diatom Cyclotella meneghiniana. (iii)–(iv) Ca fluorescence with the resolution corresponding to the size of the illumination (iii) or after iterative deconvolution (iv). Similarly, (v)–(vi) showing the Cl distribution and (vii)–(viii) the Si distribution. [Reproduced from Vine et al. (2012).] |
