Flow diagnostic instrumentation to measure turbulent flow in research and instructional wind tunnels was acquired. These instruments include a multi-channel hot-wire anemometer and a recently developed optical analysis system based on a two-dimensional Hartmann sensor. Four CTA channels for velocity and two CCA channel for temperature are included. The optical analysis system includes a PC for acquisition of phase and intensity optical measurements in a two-dimensional array. These systems provide simultaneous measurements of velocity, temperature and optical degradation in turbulent flow. Applications include optical propagation through turbulent shear flows e.g. Airborne Laser, as well as flow diagnostics for studies of the control of flow separation, transition and turbulence.
