一般注記A new and simple technical method of data acquisition by CARS (Coherent Anti-Stokes Raman Spectroscopy) thermometry was studied. 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.
