In 2006 the STFC Rutherford Appleton Laboratory began the development of the High Energy X-ray Imaging Technology (HEXITEC) detector system. Over the subsequent decade the system has delivered exceptional spectroscopic performance of < 1 keV for hard X-ray energies (2 - 200 keV) using Cd(Zn)Te sensors. With a frame rate of 10 kHz the current system is able to deliver this spectroscopic...
X-ray Edge Illumination X-ray phase contrast imaging techniques are presented with an overview of the basic principles and applications. A more in-depth discussion is dedicated to two examples where these techniques were tested outside of the laboratory to provide solution in security and in the medical field.
Recent advances in artificial intelligence, compact computing hardware, and
CMOS imaging sensors motivate physics-informed cameras (PhI-Cam). Here different
physics-driven information can come from device-specific sensor materials, sensor
architecture, electronics and noise, environmental parameters including illumination, and
degradation of the hardware performance over time. Given enough...
X-ray ptychography is a scanning coherent diffraction imaging technique that is capable of obtaining quantitative electron density maps at the nanoscale. The technique has been proven to achieve resolutions beyond the limitations of conventional x-ray optics and has been applied to a wide range of scientific fields: from life science to environmental science, and magnetism. Until now the...
