Abstract

The application of single shot coherent Rayleigh-Brillouin scattering in the accurate measurement of velocity in air and CO2 gas flows is demonstrated. Through this method, measurements are performed in the temporal rather than the frequency domain, thus allowing the measurement of velocity with very high resolution while avoiding the use of spectrometers or cameras that are typically employed in relevant studies. The successful measurement of gas flows on the order of few tens ms−1 is shown, which is verified with a pitot tube at the point of measurement.
