Group leader : Patrick Ferrand
The COMiX team is based on an interdisciplinary expertise in coherent x-ray diffraction, inverse problem and Fourier microscopy. They have pioneered development of 3D Bragg x-ray ptychography, a version of coherent diffraction imaging, which is becoming an essential tool for imaging crystalline materials.
COMiX aims at increasing the analytical capability of both x-ray and optical ptychography, by exploiting the similarities and complementarities of both (...)

Next COMiX trips : 1-7 Oct 2023, Cargese, France : Virginie Chamard, invited lecturer, Ecole CohereX - Science with coherent x-rays at 3rd and 4th generation synchrotron sources

Several works in our group share an original imaging approach called ptychography. Ptychography uses a series of diffraction patterns recorded when illuminating a sample at different locations. Then, a quantitative picture of the object (amplitude and phase) can be reconstructed numerically. Initially developed and widely exploited in electron and X-ray microscopy, it has been recently successfully extended by our pioneering work in X-ray Bragg ptychography and in optical vectorial (...)
