Gas sensors based on superluminescent diodes for combustion monitoring

Not Accessible

Your library or personal account may give you access

Abstract

Application of fiber-coupled superluminescent diodes with a wideband optical source for the detection of various gases is reported. Superluminescent diodes with two different wavelengths around 760 and 1530nm are used for O2 and NH3 gas sensing, respectively. The technique allows multiple-gas sensing for combustion monitoring.
