Abstract
PURPOSE:The captioned device which does not require parallel light beams, uses a simple light source, is inexpensibly producible and is highly accurate, by compensating the attenuation of the transmitted light owing to the scattering of the light caused by the water drops coexisting in smoke through the use of the deflection characteristics of light.
