红外光纤矿井瓦斯检测系统的试验研究

his article elaborated the infrared optical fiber damp examination system performance test as well as the methane gas density and the absorption luminous intensity relations and so on the experimental plan, the laboratory procedure and the experimental result, by confirms the optical fiber gas examination plan feasibility which this article proposed. The experimental content includes: Optical fiber link loss experiment. The photo source actuation and the phase-lock enlarge the electric circuit output wave shape experiment. Methane gas absorption signal experiment and system examination sector analysis have been done.
