Paper Abstract

In order to satisfy increasingly stringent automotive emission control laws, it is necessary to develop sensors that are capable of quantifying exactly the pollutants entering the atmosphere. The development of a mid-infrared optical fibre based sensor suitable for the detection of automotive emissions is discussed in this paper. Mid-infrared spectroscopy is deemed suitable for the task as the fundamental absorption lines of the majority of the pollutant exhaust gases are in the mid-infrared region of the spectrum. This paper focuses on the monitoring of carbon dioxide gas as it has significant absorption in the mid-infrared.
