Abstract
The US Air Force Phillips Laboratory recently completed an extensive series of flight test experiments to determine the effects of optical turbulence in the 35,000 to 47,000 foot altitude regime. The test series, known as ABLE ACE or Airborne Laser Extended Atmospheric Characterization Experiments, yielded the most precise information on the effects of stratospheric turbulence on laser beam propagation than has ever been previously obtained. The data gathered by this technology program is essential for validating laser beam propagation models and simulation tools used for designing and building the Air Force's Airborne laser. The high vibration environment of an airborne platform poses a unique requirement for scientific instruments that are designed to yield estimates of image and wavefront quality. This paper describes the primary optical sensor used to gather that data. The instrument is a differential phase measuring interferometer that is also insensitive to local turbulence effects.
