The Role of Interferometers in Future Space Astrophysics Missions
Ron Allen (STScI)
An important aspect of future space astrophysics missions
in the UV-O-IR range is the pursuit of higher angular resolution. Such missions
include the characterisation of exoplanetary systems, and imaging the surfaces of
stars. Some of the general features of interferometeric imaging systems are
discussed here, including their advantages and disadvantages. The physics of image
formation and restoration using interferometers is well understood from radio astronomy,
and a number of ground-based systems have shown that this experience is directly applicable
to the UV-optical-IR systems we hope to see in space. The challenges presently are in the
engineering. The lack of a coherent technical program to address these challenges within NASA,
the astronomy community, and Industry. is a major concern for the future.
