Concentration and temperature measurements in combustion measurements using Coherent AntiStokes Raman ScAttering (CARS) spectroscopy
Abstract
The theory underlying the coherent antistokes Raman scattering (CARS) process is reviewed and the experimental arrangement required to record the spectra of CO, CO2, H2O, N2, and O2 in cells heated to 1800 K is described. The antistokes signal is analyzed spectrally with a monochromator. Combining with this instrument a vidicon or an array of photodiodes, the entire rotovibrational spectrum of a molecular species is obtained with a single laser shot.
