摘要：

This study reports on the use of Kalman's method for filtering an experimental signal to improve the accuracy of a (CO2)-C-13-O-16 measurement in the exhaled human breath using tunable diode laser absorption spectroscopy with a semiconductor diode laser tunable near to a wavelength of 2 mu m. It is shown that Kalman's filtration allows a 5-fold increase in the detection accuracy of Co-13(2).
