Infrared instrumentation for Large Interferometric Arrays (position 2)

Printer-friendly versionPDF version

The institute is already strongly involved in several international projects e.g. for VLTI, LBT, SOFIA, Herschel, JWST, APEX, ALMA. In the context of the institute involvement in long-baseline interferometry, the 1st Physics Institute coordinates the BMBF-funded instrumentation project ALSI (Advanced Laser- writing for Stellar Interferometry) in collaboration with the University of Jena and the Max-Planck Institute for Astronomy in Heidelberg, which are among the major institutions in the field of astronomical instrumentation. The ALSI project is aiming at developing new photonic-based solutions fabricated by ultrafast laser writing techniques, which will become the future key components for interferometric multi-aperture beam combination and fringe- tracking.

Within this project, the student will develop the theory for fringe tracking at the sensitivity limit, with emphasize on group delay tracking, multi-wavelength fringe prediction, Bayesian fringe position estimation, active dispersion control.
