Investigating the Relation between Absorption and Gas Concentration in Gas Detection Using a Diffuse Integrating Cavity
The relationship between absorption and gas concentration was studied using a diffuse integrating cavity as a gas cell. The light transmission process in an arbitrary diffuse cavity was theoretically derived based on a beam reflection analysis. It was found that a weak absorption condition must be s...
