Abstract

A monitor for monitoring gas concentration in an aerospace application is described, one such application being measuring the concentration of oxygen in or next to aviation fuel. The monitor comprises: a substance, the spectroscopic properties of which change when the substance is exposed to the gas; a light source, arranged to irradiate the substance with light; and a photosensor, arranged to detect light from the substance.
