摘要：
We analyze soft x-ray images of the solar corona, obtained on the day of the solar eclipse in July 1991, and find that the deviations of our telescope mirror from the perfect surface are less than 1 angstrom for spatial periods between 1 mum and 1 mm. Our thin film deposition technique allows us to reduce errors over larger periods to the 1 angstrom level. Thus, we are able to produce large (diameter over 20 cm) x-ray mirrors with diffraction limited resolution below 0.01 arcsec.
