The paper presents a project of the system designed to NO and N2O absorption coefficients measurements. In the system was applied one of the most sensitive optoelectronic gas detection technique - Cavity Enhanced Absorption Spectroscopy (CEAS). The absorption coefficient is determined by measurements of decay time of a laser pulse reflected inside an optical cavity. The measurement procedure consists of two steps. First, in case of lack of tested gas, decay time is determined. It...
