Abstract：The consistency of gas plays an important role in the industrial production process.In this paper,laser absorption spectroscopy detection technology gas sensor system for monitoring studies.Principle of laser absorption optical fiber gas sensor was introduced,adopt a balanced detection method to overcome the laser intensity fluctuations caused by the impact of the detection sensitivity,system＇s sensitivity power is increased,and structure of the sensor was designed.Experimental results show that optical fiber gas sensor based on laser absorption detection has good detection effects,can be realized real-time detection of gas coal mines.
