Abstract—Tunable Diode Laser Absorption Spectroscopy (TDLAS) is becoming more important method to measure the physical properties in real time such as temperature, gas concentration, velocity and pressure. It is more useful in huge combustion systems because of their harsh environment conditions. And a combustion gas concentration like CO and CO2 can be a factor to indicate the energy efficiency of a combustion system. In this study, a research was carried out to calculate the respective gas concentrations of two species mixture using TDLAS method. Experiments were performed to calculate the respective gas concentrations of a mixed gas by analyzing two types of wavelength absorption signals, one gas affected absorption signal and combined absorption signal. And its results were compared with actual concentration values of the mixture. As a result, each gas concentration can be well-calculated by proposed method in this article, even if there is no independent absorption signal of a measurement target gas of the mixture.
