title: OPTICAL DEVICE FOR MONITORING CARBON DIOXIDE CONCENTRATION IN AGGRESSIVE GASEOUS ENVIRONMENTS
abstract: Accurate determination of the concentration of components in flue gases is a critically important aspect for ensuring the efficiency and safety of industrial processes. In today's world, with increasing demands for environmental safety and energy efficiency, the control of harmful gas emissions is becoming increasingly significant. In particular, the accuracy of measurements of flue gas component concentrations, such as carbon dioxide (CO2), nitrogen oxides (NOx), and other pollutants, not only
