Compressible Flow Field

Our group employs fundamental theory and computational techniques for aberrating flow fields. We work to better understand and predict the distortion of optical signals by turbulent flow, paying particular attention to the performance of airborne laser systems for communication, target tracking, and directed-energy weapons. We have played key roles in developing numerical simulations and wave-front devicesthat allow measurements of instantaneous wave-front errors in unprecedented detail, including a small-aperature beam technique sensor and an analog-only Shack-Hartmann wave-front sensor.
