  • Method and apparatus for precipitation detection and differentiation
    Patent number: 5557040
    Abstract: A direct backscatter technique provides for the detection of precipitation in a measuring volume. A source light beam is projected into the measuring volume. Light in the volume, including source light scattered from any precipitation within the volume, is collected and detected. A signal is generated corresponding to the detected light. This signal is used to determine whether precipitation is present in the measuring volume. The light scattered from precipitation within the measuring volume may also be used to differentiate between types of particles. Rain and snow, for example, can be differentiated based on whether the transmitted light changed from its original polarization state.
