Abstract
Athena is ESA’s X-ray observatory mission designed to address the Hot and Energetic Universe theme. The instrument consists of a single x-ray telescope, supported by a large area mirror focusing the photon flux alternatively onto two different instruments The process of switching the focus between the two instruments is produced by changing the pointing of the main X-ray mirror. The verification of the alignment of the mirror optical axis with respect to each of the instruments with accuracy better than 0.5 arcsec is achieved by means of an optical On-board Metrology System (OBM).
In this work we will present the experimental setup and processing architecture designed for calibration and testing the OBM demonstrator allowing to evaluate the performance of the on-board metrology system for the Athena X-ray Observatory mission.
