Abstract

Dual-broadband pure rotational coherent anti-Stokes Raman scattering is a valuable nonintrusive tool for gas diagnosis that provides simultaneous and time-resolved information about temperature and relative species concentration. A systematic investigation of single-shot precision and accuracy of simultaneous measurement of temperature and O2/N2 concentration is presented. Various O2 concentrations (1.0–15.6%) in binary mixtures with N2 have been investigated in a temperature range from 300 to 773 K and for pressures of 1–50 bars (0.1–5 MPa). A comparison of two least-sum-squared differences fit evaluation procedures for the spectral shape, weighted constantly or inversely with respect to the relative signal intensity, is given. The results yielded good accuracy and precision for measuring temperature as well as concentration. The influence of temperature, O2 concentration, pressure, and evaluation techniques on both accuracy and precision is discussed.
