Holography of the Onsala Twin Telescopes
Year: 2025
Type: article
Abstract: We present recent results from dual polarized beam holography of both the Onsala Twin Telescopes (OTT) carried out with Geostationary satellites as the source. Through the recent measurements, we obtain both co- and cross-pol beams for the OTT. From refined calibration methods, we find an efficiency of 45 %, and an rms path length < 3mm.
