Abstract
Light scattering from laser-induced electrostrictive gratings has been used
for simultaneous, instantaneous, nonintrusive, and remote measurements of
temperature and velocity in a submerged air jet. We accomplished phase-sens
itive detection of scattered light by superimposing two signal beams whose
frequencies mere Doppler shifted by the movement of the grating. Temperatur
es in the range 295-600 K and flow velocities in the range 10-100 m/s were
measured. (C) 2000 Optical Society of America.
