| Zusammenfassung |
| Laser interferometry will play a key role in the next generation of GRACE-type satellite
gravity missions. The measurement concepts for future missions include a heterodyne laser
interferometer. Furthermore, it is favourable to use polarising components in the laser
interferometer for beam separation. Therefore the influence of these components on the
interferometer sensitivity has been investigated and a length stability on a pm-scale has been
validated. The design and construction of a quasi-monolithic interferometer for comparing
the interferometric performance of non-polarising and polarising optics will be discussed.
The results of the interferometric readout of a heterodyne configuration together with
polarising optics will be presented. |
