Study on Absorption Signal Interference of Gas Concentration Measurement Using Laser Absorption Spectroscopy

In order to optimize the combustion condition of the combustion system, it is important to know the information of the physical properties which vary during combustion. Gas concentration and temperature are the major target properties but it is difficult to measure exactly at combustion system. In t...
