Description
Summary:A new approach to the investigation of the quality of concave spherical surfaces has been proposed and experimentally implemented for the first time. This approach is based on the whispering gallery effect in the X-ray wavelength range. One distinctive feature of the technique proposed is the application of algorithms of computed tomography for locating surface defects and describing their shape. It is noteworthy that the sizes of surfaces and their radius of curvature are not restrictive factors for this analysis.
