Optical Engineering: The Journal of SPIE, 2019 . Wavelets shrinkage is the most illustrative of wavelets transform for speckle noise reduction. We aim to study the performance of a monogenic wavelet transform to reduce the speckle noise in digital speckle pattern interferometric fringes. The proposed

Journal of Synchrotron Radiation, EarlyView.The evolution of hierarchical phase‐contrast tomography (HiP‐CT) from its origins at the BM05 beamline to its transition to BM18 (ESRF‐EBS) is shown. The novel hardware and scanning approach developments resulted in significantly improved data quality, resolution, sensitivity and speed.

Journal of Microscopy, EarlyView.Abstract X‐ray phase contrast imaging (XPCI), when implemented in micro‐computed tomography (micro‐CT) mode, offers high‐contrast 3D imaging of weakly‐attenuating material samples. In the so‐called single‐mask edge illumination approach, a mask with periodically spaced transmitting apertures is used to split the x‐ray beam into narrow beamlets; when ...
