Third telescope project at the IOTA interferometer
Abstract
The third telescope project to enable phase-closure observations at the IOTA interferometer is well underway, and is anticipated to be completed later this year. For this project, we present the main technical improvements which we have already made or expect to make, including a new VxWorks control system, improved star acquisition cameras, improved siderostat and primary mirror supports, five-axis control of the telescope secondary mirrors, automated control of the long delay line, trihedral retroreflectors, three-beam combination, the PICNIC camera, and fringe packet tracking.

We are grateful to NASA for funding (NAG5-4900) the hardware required for the 3rd telescope upgrade at IOTA, and for supporting the fringe-packet tracking work for IOTA at SAO and NASA-Ames. We also gratefully acknowledge ongoing institutional support from the Smithsonian Astrophysical Observatory and the University of Massachusetts at Amherst.Attached Files
