Phase masks in astronomy: From the Mach-Zehnder interferometer
Laboratoire d'Astrophysique de Marseille,
2 place Leverrier, 13248 Marseille Cedex 4, France;
Phase masks have numerous applications in astronomical optics, in
particular related to two themes: coronagraphy for detection and
analysis of extrasolar planets or circumstellar disks, and
wavefront analysis for extremely precise adaptive optics systems
or cophasing of segmented mirrors. I review some of the
literature concerning phase masks and attempt to bridge the gap
between two instrumental systems in which they are often found:
the Mach-Zehnder interferometer and the coronagraph.
