Abstract : This patent discloses an apparatus for determining the liquid water contents (LWC) of a sample gas having water droplets suspended therein includes a light source for passing a collimated light beam through the sample gas, and a sensor for detecting the light scattered by the water droplets. The sensor includes a photodetector having a planar light sensitive surface positioned to receive scattered light. A light trap is also provided between the photodetector and the light source for blocking nonscattered light in the light beam from the photodetector. The light flux detected by the photodetector is proportional to LWC.
