Promising methods for quality control test of large convex aspherical mirrors
Engineering Education # 12, December 2013
DOI: 10.7463/1213.0645432
Promising methods for quality control test of large convex aspherical mirrors were considered in this article. These methods are based on a new scheme of illuminating the mirror under control by a parallel multiple-beam where the beams are perpendicular to the mirror’s symmetry axis. The main advantage of such methods is that they don't require auxiliary large-size optical elements. A new non-interferometric method for a quality control test of convex aspherical mirrors with high aperture (angle between the optical axis and the marginal normal to the mirror is more than 45 degrees) was developed on the basis of the specified illuminating scheme.
