Workpackage 5 : Paving the way towards femtobiology

Fig.1 Image of spider wire recorded with an optical microscope. The wire is 1 µm thick.

Fig.2 Raw image of the XUV hologram of the spider wire (fig.1) achieved with HHG beam.

Fig.3 Movie of the amplitude field as reconstructed from the hologram of the spider wire (fig.2). Each image corresponds to a different depth of focus. The sharpness of the image corresponds to the best image plane. Since the wire is rolled up, the different portions are not sharp at the same planes demonstrating the quasi-3D image recontruction.

Fig.4 Picture of a wire obtained with an optical microscope.

Fig.5 Raw hologram of the test wire (fig.4). The fringes are highly constrasted even up to the 20th ensuring a high spatial resolution of the reconstructed image.

Fig. 6 Movie of flash imaging at DESY. 2D hologram reconstruction is viable after irradiating with an ultra-bright XUV pulse destroying the sample. For more details see Chapman et al, Nature Physics 2006.
