Methane and carbon dioxide detection using LED sources

Notes the advantages of the use of LED sources in the detection of flammable gases, suggesting they contribute towards factors such as high sensitivity and low power consumption. Focuses on two detection techniques: the gas correlation optical system and the filtered gas detection technique. Looks at the operation of LED sources in relation to these techniques and the development of 3.3 and 4.3 micron LED sources. Notes the results of tests on such LED sources, asserting the feasibility of a low power consumption, LED‐based detection system.
