Abstract : Light shown through a space containing smoke or an aerosol is detected from several paths through the space. The light may be gathered from physically separated optical fibers feeding a common photodetector, or several physically separated, series-connected photodetectors may be used. The total amount of light reaching the photodetector(s) is directly related to the average density of the smoke or aerosol. (Author)
