dc.description.abstractThis paper reports on the application of the Kalman method for processing the signal obtained by the tunable diode laser absorption spectroscopy method in an experimental circuit, which includes the frequency modulation of a diode laser pump current in combination with the synchronous detection technique. It has established that the implementing of this approach makes it possible to improve the measurement accuracy of the (CO2)-C-13 content, as well as the measurement accuracy of the (CO2)-C-13 and (CO2)-C-12 concentrations ratio in exhaled air to a level not exceeding 0.1%.
