Revolution in X-ray Optics

N.M. Ceglio

In the past decade, there has been a technological revolution in our ability to generate, control, manipulate, focus, and detect x-rays. The past few years have been witness to significant advances in the development of normal incidence x-ray mirrors and beam splitters, diffraction limited x-ray microscopy, x-ray holography, x-ray waveguides, and CCD x-ray detector arrays. Using these new capabilities, workers in the field are taking the first steps toward the development of sophisticated soft x-ray optical systems, including soft x-ray interferometers, high-intensity x-ray lasers, and projection optics for x-ray lithography.
