MODULATION LASER SPECTROSCOPY METHOD FOR IR-RADIATION LOSES MEASUREMENTS IN GASES
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2014, Vol 11, Issue 2
Abstract
This paper provides analysis related to modulation laser spectroscopy method (MLS) with utilization of direct Fourier transform for determination of either loss coefficient or gas concentration in the mixture. Applicability of approximate analytical equations that are used for low attenuation in gases with two level absorption was appraised for high absorption coefficients or concentrations. Analysis of frequency related power dependence of the laser source and its influence on calculated accuracy of abovementioned parameters is also provided in this work
