Аннотация
It has been shown clearly that using the synchronous detection technique with the pump current frequency modulation of a tunable diode laser emitting near 2 mu m wavelength, combined with the application of the Wiener filtering algorithm for the experimental signal, ensures a two-times improvement in the measurement accuracy for the (CO2)-C-13 content in exhaled air, and, for the (CO2)-C-13 and (CO2)-C-12 concentrations ratio, more than seven times.
