Abstract

The theory of temperature and density measurements of air flow by Rayleigh scattering and UV (193 nm) laser-induced oxygen molecules fluorescence (LIF) are studied. This method befits to instantaneous two-dimensional temperature and density measurements of air and Oxygen flow. The Rayleigh scattering of room air as well as oxygen flow LIF image are observed by an intensified CCD videocamera (ICCD) system. The two-dimensional flow parameter is obtained after image process.
