| Abstract: | The principle of the differential optical absorption spectrometry (DOAS) is presented.The design of the device integrating transmitter and receiver and the method to obtain the concentrations of several gases simultaneously in the same waveband are also described.The system is used to perform long-term monitoring of ambient SO-2,O-3 and NO-2,and the results are shown to be practical. |
