Raman spectroscopy has the potential of providing detailed temperature and composition measurements at discrete points within a mixture of gases. Although cross sections for Raman scattering are characteristically very small, recent developments in high power lasers and sensitive optical detectors have resulted in the application of Raman spectroscopy to a variety of new experimental studies. Current applications include the remote measurement of atmospheric constituents and temperatures, concentration measurements in heterogeneous, nonreacting gasdynamic processes, remote detection of pollutants in gas turbine exhaust, and temperature and composition measurements in steady flame gases.
