摘要提出了一种新的密度涨落时空分辨测量技术。它是非侵入式的，基于激光多普勒测振仪。密度波动揭示了动态热释放和流体速度的信息。通过在模型燃烧室中记录热声振荡，证明了这种技术的重要性。
Abstract A novel technique for time- and space-resolved measurement of density fluctuation is presented. It is nonintrusive and based on laser Doppler vibrometry. The density fluctuations reveal information on dynamic heat release and fluid velocity. The significance of this technique is proven by recording thermo-acoustic oscillations in a model combustor.
