An infrared gas monitor employing temperature modulation of the source emission spectrum

Research output: Contribution to journalArticle

Abstract

A novel infrared gas monitor is described which provides both sample and reference channels in a single optical path but which has no moving parts. The emission spectrum of the filamentary source is modulated by varying the source temperature, and wavelength selection is provided by an optical interference filter possessing two passbands. The detection of methane is demonstrated using a simple experimental arrangement.
