The error of this conventional approximation is controlled by the ratio of the source size to the smallest feature in the object, as is shown by numerical simulation. In a second step, we investigate how to overcome the flawed empty beam division by simultaneous reconstruction of the probing wavefront (probe) and of the object, based on measurements in several detection planes (multi-projection approach).

Aberrations inherent to the illumination can mix with the features imposed by the object. Conventional raw data processing methods rely on the division of the measured hologram by the intensity profile of the probe and are not able to fully eliminate artifacts caused by the illumination. Here we present a generalized ptychography approach to simultaneously reconstruct object and probe in the optical near-field. Combining the ideas of ptychographic lateral shifts of the object with variations of the propagation distance by longitudinal shifts, simultaneous reconstruction of object and probe was achieved equally well for a highly aberrated and a mildly disturbed probe without the need for an additional wave front diffuser. The method overcomes the image deterioration by a non-ideal probe and at the same time any restrictions due to linearization of the object's transmission function or the Fresnel propagator. The method is demonstrated experimentally using visible light and hard x-rays, in both parallel beam and cone beam geometry, which is relevant for high resolution x-ray imaging.

A1-mm biopsy punch was taken from the paraffin blocks and\r\nplaced into a KaptonVR tube for subsequent tomographic investigation. The samples were scanned,\r\nwithout further preparation, using phase-contrast tomography at two different scales: overview scans\r\n(performed with laboratory setups), which allowed localization of the nervous tissue ( 1mm effective\r\nvoxel size); and high-resolution scans (performed with a synchrotron endstation), which imaged localized\r\nregions of 320x320x320 mm3 (176 nm effective voxel size).\r\nResults: The contrast allowed us to follow the shape and the size changes of the ganglia, as well as\r\nto study their cellular components together with the cells and cellular projections of the periganglional\r\nspace.
