Abstract
LAM is developing a high-contrast imaging testbeds for in-lab demonstration of new instrumental concepts requiring high contrast imaging: in particular, for solar and stellar coronagraphy applications. In such applications, a faint target has to be detected close to a very bright source. For these test-benches, a high-dynamic range detector is required to characterize and/or to determine the performance of a new concept. Beyond the capability to detect the target, an imaging detector has to be accurate, reliable and provide reproducible performances. In order to identify a commercial camera for the development of laboratory demonstrators working with high contrast scenes, we carried out a test campaign at the Laboratoire d’Astrophysique de Marseille (LAM) evaluating several cameras implementing different detector technologies. This paper presents the results of the test campaign, carried out at LAM, providing a quantitative comparison between the investigated technologies
