The measurement of the relative concentration of small particle groups has promising application prospects in the research of atmosphere, industrial burners, chemical factories and fire science. This paper introducos a kind of fiber optic smoke sensor which is used to measure the optical density of the smoke. This apparatus is of great usefulness specially in the hazardous and hostile environments. Experiments had been done to measure the optical density of the fire smoke with this apparatus.
