Abstract: |
Enhancing the limiting sensitivity of optical/infrared interferometers
is the major task for today's array designers. Often the array
sensitivity can be compromised by the inability of one sub-system to
match the sensitivity of the others in the array. In the case
of very red targets, e.g., with V–K ≥3, the visible light fast
tip-tilt (FTT) systems typically used at each unit telescope (UT) can
easily be the limiting factor. This can have a severe impact on the
ability of an array to pursue AGN, YSO and brown dwarf science.
Here, we outline how the Magdalena Ridge Observatory Interferometer
(MROI) has overcome this problem and report on progress with the
delivery of its sensitive FTT system currently being developed
in Cambridge, UK. |
