Nová měřící metoda tvaru konkávních zrcadel na principu digitálního zpracování Hartmanova testu

The theory, optical, mechanical, and software design for a special Hartmann wavefront analyzer is presented. This method is applied for the non-contact method of concave mirrors shape measurements. The so-called Hartmann test is used with the digital image reading and the fast computer data evaluation. In this method a transparent spatial modulator is used instead of binary mask. Our institute Joint Laboratory of Optics produces segmented mirrors for the Pierre Auger observatory fluorescent detector [1]. We use this method as the qualitative measuring of this spherical mirror segments. These segments are unique because they are light and ultrathin. The production of mirrors is based on standard operations commonly used in the optical industry (cutting, drilling, milling, grinding and polishing), with the difference that they are extremely thin. This fact can cause segment shape instability in the production process
