| Abstract: | In view of the detection principle of fiber-optical gas sensor, a new gas sensor system combing two detection principles is studied. According to the method of infrared spectrum absorption and the use of LED light source, the dual-wavelength differential detection structure and harmonic detection principle are adopted together. The examination shows that the method can improve the reliability of the system and reduce the system errors. |
