The proposed method provides instantaneous temperature determination with quick measurement of an intensity ratio of N2 CARS spectra by the use of a specially prepared monochromator, two photomultiliers and a data processor including an A/D converter, a circuit for sampling-hold mechanism and a personal computer. This method is capable of providing close to real-time temperature measurements for high rate of laser shot repetition, and the remarkable cost redution of optical and electronic instruments. The measured results were compared and verified with a thermocouple (< 1200K) and the conventional multiplex CARS method (1600~2000K). Various causes of, and their cotributions to, the measurement errors introduced into the instruments were evaluated experimentally. Application to a practical burner was made with reasonable results., 資料番号: NALTR0999000, レポート番号: NAL TR-999}, title = {A SIMPLIFIED CARS THERMOMETERY FOR PRACTICAL USE}, year = {1988} }
