Abstract / Description: 

The field of X-ray imaging has not only contributed to a wide range of basic sciences, but also many industries, such as medical imaging, non-destructive testing, and security. Due to the ability to image through thick objects with high resolution and in some cases, with elemental identification and femtosecond time resolution, x-ray imaging in biological, chemical, and physical sciences is a very powerful tool. Examples of this include tomography of whole unstained cells, in-situ nanoscale imaging of battery components with elemental specificity, and imaging of magnetic domains. While sophisticated x-ray instrumentation has been developed for use with synchrotron radiation, translation to lab-based use still remains a challenge. A major goal in x-ray imaging is to be able to develop new lab-based technologies with improved imaging capabilities that currently exist at synchrotrons. In the first part of the talk, I will describe our developments in x-ray imaging concepts, x-ray structured illumination, hybrid imaging schemes, Fourier and iterative-based optics designs, and enabling nanofabrication methods, with primary applications using synchrotron and free electron laser radiation. In the second part of the talk, I will describe new directions and technologies for translational research with potential applications in x-ray biomedical imaging and x-ray metrology.
