The Waves Michelson Interferometer (WaMI) is designed to make wind measurements of the atomic oxygen green line (557.7 nm) emission, a molecular oxygen line at 1264 nm, and a hydroxyl line at 1315 nm. These emissions provide a capability for probing the dynamics of the middle atmospheres of the terrestrial planets. The special feature of the design of this instrument is that the back mirror is a quad mirror configuration. As a result four fringe phase images can be generated simultaneously thereby eliminating the effects of irradiance variations during the integration time. The WaMI is currently set-up in a laboratory environment, with a retro-reflective wheel used to simulate Doppler winds. Results of the step size calculations, as well as, wind wheel measurements will be presented. These validate the use of this instrument as a monolithic instrument capable of measuring winds without mirror scanning for ground based and satellite applications.
