Abstract : The patent describes a method and apparatus for measuring the density size, shape and distribution of rain, snow, hail, sleet and the like in the atmosphere. A preferred embodiment of the apparatus uses a gated image (channel plate) intensifier mounted in an aircraft and an outboard high intensity light. The light establishes a defined volume which is examined by the image intensifier for a time interval on the order of a microsecond or less. The image is retained by the intensifier tube while a high speed camera or other means photographs or scans the surface to provide a record.
