title: A phase-space approach to x-ray optics.
abstract: The basic concepts and properties of some phase-space mathematical functions, in particular of the Wigner distribution function, are reviewed. Then, the propagation and diffraction of x rays are considered from the point of view of the Wigner function, resulting in a simple method consisting in coordinate shifts in phase space, which can be easily implemented in a personal computer. The applications of this tool to x-ray technology are also discussed.
