| Zusammenfassung | In dimensional measurements by laser interferometry, when the accuracy approaches 10-9 λ, wavefront aberra tions cause systematic variations of the fringe period. This paper illustrates how these effects are modeled and experimentally studied in the measurements of the lattice parameter and the topographical survey of 1 kg Si spheres, which measurements are necessary to "count" atoms and to make it possible to realize the kilogram from the Planck constant value. |
