Optical flatness standard
Description
Matters relevant to preparing an optical flatness standard are discussed, such as selection of the material, surface preparation, bulk viscoelastic deformation, thermoelastic deformation, refractive errors, reduction of interferograms of plates examined in pairs, absolute calibration by intercomparison of two flats examined in two orientations, and the combination of several contours to obtain the figure of the plate. The contours are given as Fourier sine series expansions, and a technique for obtaining the coefficients is described
