A spectrally resolved Rayleigh/Mie scattering diagnostic was developed to measure temperature and wing span wise velocity in the vicinity of an ASTOVL aircraft model tested in the Lewis, now Glenn, 9x15 Low Speed Wind Tunnel. Shown is a Fabry-Perot interferometer that uses only the blue light from a laser to measure static temperature and velocity near the lift nozzles and suction systems.
