Abstract

Planar laser-induced fluorescence of O2 has been used to acquire quantitative, instantaneous two-dimensional images of temperature in heated air flows. O2 is excited by using a broadband ArF excimer laser at 193 nm, and the resultant fluorescence signal is converted to temperature by using a theoretical calculation of the dependence of the fluorescence on temperature. This calculation has been confirmed experimentally, and validating data are presented.
