3.5 Correction of wave fronts

3.5.1 Problem of producing wave fronts

To solve a wide range of problems in astronomy, optical instrument making and optical processing of information, it is necessary to produce high-quality aspherical surfaces, for example, parabolic optics for large telescopes. The formation of high quality aspherical surfaces depends on the development of efficient methods of attestation of these surfaces [7882]. These methods are based on the formation of reference wave fronts whose shape corresponds to the surface to be inspected. The spherical flat wave fronts form naturally in classic optical systems, consisting of lenses, prisms and spherical mirrors. The formation of reference wave fronts of a more complicated shape ...
