An Infrared Absorption Gas Detection System Applying Plane Blazed Grating

Abstract:

Article Preview

Quick, accurate and reliable detection of mash gas plays an important role in the coal industry. This paper presents a novel method to get the infrared absorption peak wavelength by light splitting using plane blazed grating, instead of using filter conventionally. The principle and setup of producing 3.433μm and 4.65μm wavelength lights for detecting CH4 and CO concentration are described in details. The work provides a simple, but efficient option to the infrared absorption gas detection technology.
