| Zusammenfassung | To realize SI-traceable length measurements in air over distances of up to 5 km with a relative uncertainty significantly better than 1 part-per-million (10-6), we develop an outdoor-capable heterodyne interferometer. Beam guidance in two levels enables a compact design. We use a closed frame design to ensure high mechanical stability, and low thermal expansion materials to avoid mechanical drifts. An optimized fixation of the optical components and flexure hinges ensure long-term stability of the optical set-up. Besides stability, another challenge addressed is the fact that the system requires alignment capabilities to better than 0.5 arcseconds. |
