Abstract

NASA’s latest and most ambitious flagship space observatory, the $10 Billion dollar James Webb Space Telescope (JWST) represents such a major step in capability that it is difficult to identify any area of astronomy that will not undergo a profound change following its successful December 2021 launch and subsequent deployment. The recovery of images of exoplanets and their environments is among the key scientific drivers for which the mission was built. In 2008 a dedicated interferometer, designed by the authors, was accepted by the JWST NIRISS Instrument Team based in Montreal, adding Aperture Masking Interferometry (AMI) to JWST’s suite of modes. Fabricated in Canada and tested by Honeywell and CSA as well as NASA, it is now one of JWST’s supported scientific modes. Here we provide a high level description of the mode, and the science themes that originally motivated it.
