| Zusammenfassung | Determination of the roughness correction with a scattering light method is preformed at PTB since more than forty years for measurements of gauge blocks by interferometry. Setting up of a new integrating sphere initiated investigations on calibration methods. The coupled interferometer method and the Newton's ring method are described and compared. For the coupled interferometer method, the gauge blocks are wrung to an optical flat and the phase of reflection for the gauge-flat interface is determined in a Twyman-Green interferometer. Satisfactory agreement is obtained for the result with both methods. |
