Accessing High Spatial Resolution in Astronomy Using Interference Methods
Peer reviewed Peer reviewed
Direct linkDirect link
Carbonel, Cyril; Grasset, Sébastien; Maysonnave, Jean – Physics Teacher, 2018
In astronomy, methods such as direct imaging or interferometry-based techniques (Michelson stellar interferometry for example) are used for observations. A particular advantage of interferometry is that it permits greater spatial resolution compared to direct imaging with a single telescope, which is limited by diffraction owing to the aperture of…
