This arrangement was effective in eliminating nonresonant signals generated in the light path and was capable of keeping the signal levels higher than BOXCARS arrangement. It was shown that by single-pulse measurements the lowest detection level of O2 concentration was possible down to 2% volumetric fraction. A nonresonant background suppression technique was also attempted and background-free specta of O2 and CO were obtained to demonstrate the background rejection ability and the enhancement of detectivity., 資料番号: NALTR0940000, レポート番号: NAL TR-940}, title = {CARS Measurements of Combustion (II) Gas Species Concentration Measurements}, year = {1987} }
