Abstract
A method for analyzing a gaseous sample, by comparing an incident light wave and a transmitted light wave, the method comprising: i) illuminating the sample with a light source emitting the incident light wave propagating up to the sample; ii) detecting a light wave transmitted by the sample; iii) detecting a reference light wave emitted by the light source and representing a light wave reaching a reference photodetector without interacting with the sample; iv) repeating i) to iii) at different measurement instants; v) estimating, at each measurement instant, an intensity of the reference light wave; vi) taking into account the estimated intensity of the reference light wave and the detected intensity of the transmitted light wave to perform a comparison, at each measurement instant; and vii) analyzing the gaseous sample as a function of the comparison.
