Photonic component for an astronomical interferometer
Three working groups from Heidelberg, Cologne and Potsdam are involved in a joint project to develop a new technology for astronomical research. The researchers intend to render micro-optic systems used in telecommunications suitable for use in large telescopes. The collaborative project is being supported by the Königstuhl State Observatory of the Centre for Astronomy of Heidelberg University, the Institute of Physics I of the University of Cologne, and the Leibniz Institute for Astrophysics in Potsdam. The German Research Foundation (DFG) has approved funding of approx. 1.1 million euros for the three-year project, which recently started work. Operating principle of a photonic reformer. In this example, a squared field of view is converted into a thin line, which can be very effectively coupled into an astronomical spectrograph. The 'Novel Astronomical Instrumentation through Photonic Reformatting' (NAIR) project is being funded by the DFG within the 'New Instrumentation for Research' call for proposals.
