| Abstract: | Spectrum analysis technology has a broad prospect of application in air pollutant monitoring field.Based on the principle of absorption spectroscopy,this paper proposed a new experimental scheme of using hollow-core photonic crystal fiber for pollutant detecting in air.By measuring the absorptance of sample gases,such as methanol and trichloroethylene with different concentrations,it is found that the detection sensitivity of our experimental setup can achieve ppmv level according to the 3 sigma criteria. |
