Abstract

Due to the photosensitive properties of toxic and harmful gases themselves and the complexity of the specific gas composition in enclosed spaces, the reliability of the detection results of target gas content is difficult to guarantee. Therefore, a method for detecting toxic and harmful gas content in enclosed spaces based on fiber optic SPR gas sensors is proposed. Using wavelength modulated fiber optic SPR sensors as specific data acquisition devices, guided by detection requirements, combined with the theoretical basis of evanescent wave vector and Maxwell equation equality, the fiber optic SPR sensors are modulated to obtain reliable basic data. The Lorentz line shape is selected as the absorption spectrum line for the toxic and harmful gas to be tested. By calculating the drift of the resonance wavelength, the content of the toxic and harmful gas medium to be tested can be determined. In the test results, the error of the detection results remained stable within 3.0ppm, indicating high reliability.
