| Abstract: | A spontaneous Raman imaging system which can monitor the concentrations of major species in flow field in real time has been described. The results of the low pressure O2 are presented and the lowest pressure we measure is 133Pa. This technique can be calibrated in real time by an introduction of a known amount of N2. The error is less than 8%. The measurement precision of O2(a1Δ) concentration will be improved largely when this technique is applied to monitor chemical oxygen-iodine laser singlet oxygen generator performance. |
