Abstract:
A method of measuring a concentration of NO2 in a gaseous mixture using a multimode laser beam that covers a tunable spectral range with a width of no more than 5 nm, wherein the multimode laser beam provides a high resolution transmittance spectrum at an absorption cross section of NO2 molecules, and a system for measuring the concentration of NO2 in the gaseous mixture. Various combinations of embodiments of the system and the method are provided.
