The patented Nanoconverter is as planar flexure-based structure that attenuates linear movement amplitudes by a large constant reduction factor that can be chosen by design typically between 20 and 1000. It allows using conventional commercial actuators wi ...
There is no doubt that optical coherence tomography has become an important biomedical imaging tool today especially due to recent improvements in detection as well as fight source technology. OCT achieves resolution in tissue of a few micrometers and can ...

X-ray radiographic absorption imaging is an invaluable tool in medical diagnostics and materials science. For biological tissue samples, polymers or fibre composites, however, the use of conventional X-ray radiography is limited due to their weak absorptio ...
The present thesis develops some specific aspects of digital holographic microscopy (DHM), namely the effect of shot noise on the phase image accuracy, the use of DHM in micro-tomography and in aberrations evaluation of a microscope objective (MO). DHM is ...
We have developed a method for X-ray phase contrast imaging, which is based on a grating interferometer. The technique is capable of recording the phase shift of hard X-rays travelling through a sample, which greatly enhances the contrast of low absorbing ...
Digital Holographic Microscopy (DHM) is a powerful imaging technique allowing, from a single amplitude image (amplitude and phase), reflected acquisition (hologram), the reconstruction of the entire complex wave front by or transmitted through an object. B ...
To date, no phase shifting technique has been implemented that accommodates the requirements inherent in holographic moiré . In the present form of measurement, only the value of one component of difference in displacement carried on moiré is quantified, w ...
In the last decade X-ray imaging based on phase contrast greatly advanced thanks to the use of unmonochromatic synchrotron hard X-rays. The recent advances are going beyond microradiology and microtomography to reach nanometre scale. This paper reviews bas ...
A simple imaging setup based on the principle of coherence-based contrast X-ray imaging with unmonochromatized synchrotron radiation was used for studying mammographic phantom and human breast specimens. The use of unmonochromatized synchrotron radiation s ...
