This will be performed by using a filter wheel with a large heritage having a set of positions for the calibration and the observation systems. In particular, it will allow for correcting possible gain variation, for measuring the modulation factor using a polarized source, for removing non interesting bright sources in the field of view and for observing very bright celestial sources. The on-board calibration system is composed of three filter wheels, one for each detector and it is expected to operate for a small number of times during the year. Moreover, since it operates once at a time, within the observation mode, it allows for simultaneous calibration and acquisition from celestial sources on different detectors. In this paper we present the scope and the requirements of the on-board calibration system, its design, and a description of its possible use in space. <P />||Conference Name:||Space Telescopes and Instrumentation 2016: Ultraviolet to Gamma Ray||Conference Place:||Edinburgh, UK||Conference Date:||26 June-1 July, 2016||URI:||http://hdl.handle.net/20.500.12386/24955||URL:||https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9905/1/The-on-board-calibration-system-of-the-X-ray-Imaging/10.1117/12.2233448.full||ISSN:||0277-786X||ISBN:||9781510601901||DOI:||10.1117/12.2233448||Bibcode ADS:||2016SPIE.9905E..4HZ||Fulltext:||open|
