AB: A prototype optical instrument for the simultaneous observation of airglow intensities and winds, through doppler shifted emission lines, has been designed and is currently operating at York University. The Mesospheric Imaging Michelson Interferometer (MIMI) has successfully retrieved simulated winds in the laboratory using visible wavelengths with an error less than 1 m s$^{-1}$ and in the near-IR region to better than 2 m s$^{-1}$. The instrument operating theory and four point wind retrieval technique will be discussed in addition to current work focusing on efforts to observe winds from a ground based instrument.
