Analysis of multiple diffraction images provides high contrast, high quality, full field 3D imaging of surfaces illuminated by extreme ultraviolet photons from a tabletop laser.

In an optical telescope, photons strike a mirror or lens whose surface is nearly perpendicular to the light's path; but extreme ultraviolet photons hitting such a surface would get absorbed rather than reflected.
