Abstract

A gas temperature measurement technique, based on the inversion of the spectral shape of a vibration–rotation absorption line, is presented. A tunable diode laser system is used to record the fully resolved spectral shape. A precise calibration of the method is given in the 300–900 K temperature range. The method is used in channel laminar air flows in which temperature is the only unknown quantity. The intrinsic uncertainties of this technique are estimated to ±2% at 300 K and ±3% at 900 K. Good agreement between the diode laser measured profiles and theoretical predictions is obtained.
