Diffraction-limited observations of astronomical sources with a rotation shearing interferometer in the near infrared
An experiment aimed at diffraction-limited imaging of astronomical sources in the 2-5-micron range is presented. It is based on a rotation shearing interferometer that produces fringes in the pupil plane that can be scanned through the zero optical path difference. The two-dimensional interferograms are recorded with an infrared camera looking at
