The International Workshopo on Astronomical X-Ray Optics took place in Prague during the second week of December 2010. Its goal was to present and discuss recent and forthcoming technologies for future X-ray astronomy missions, with an emphasis on IXO of ESA/NASA/JAXA. These missions require development mostly of innovative technologies, and invited speakers discussed the possibilities, results obtained so far, and new ideas in detail. It is ovious that the requirements of future large space X-ray astronomy missions are so demanding that they need a truly interdisciplinary approach through wide international collaboration. The technologies will include X-ray optics based on Si wafers, advanced glass forming for precise X-ray optics, but also other possible technologies, as well as related advanced metrology, measurements and tests. and Jana Poledniková.
