摘要：
Dual-broadband coherent anti-Stokes Raman scattering (CARS) spectroscopy of the Q(01)-branch of H-2 has been employed for thermometry in an atmospheric-pressure hydrogen-oxygen flame. The aim was to investigate the applicability of the technique for single-shot temperature evaluation and to analyse the precision of the measurements. The results are presented of temperature and relative H2 density mapping of the flame in the temperature range of 700-2800 K. The achieved precision of single-shot measurements was 3%-5%.
