摘要

Kalman adaptive filtering was applied for the first time, to our knowledge, to the real-time simultaneous determination of water isotopic ratios using laser absorption spectroscopy at 2.73 μm. Measurements of the oxygen and hydrogen isotopologue ratios δ O18, δ O17, and δ H2in water showed a 1−σprecision of 0.72‰ for δ O18, 0.48‰ for δ O17, and 0.84‰ for δ H2, while sampling the output of the tuned Kalman filter at 1 s time intervals. Using a standard running average technique, averaging over ∼30 sis required to obtain the same level of precision.
