DECREASING THE THRESHOLD OF THE SPECTRAL DETECTION OF MOLECULAR IMPURITIES IN GAS MIXTURES BY THE INTERFERENCE MULTIPLEXING METHOD
Abstract
The most probable ways to significantly increase the sensitivity of spectroscopic methods for detecting and measuring trace concentrations of greenhouse gas molecules in the atmosphere are considered. The basis of the proposed methods is the addition of light flows of a set of spectral components of a given molecule on a single photodetector by using the transmission spectrum features of devices using the effects of multipath interference.
