Abstract
Provided is a disdrometer system having a three-dimensional laser array unit, including: a plurality of laser transmitting parts which are arranged on an inner side of a cylindrical body to generate a laser beam; a plurality of laser receiving parts which are arranged on the inner side of the cylindrical body to correspond to the laser transmitting parts; and a laser control part which converts a cut-off signal of the laser beam, which is cut-off by precipitation drops flowing into the inner side of the cylindrical body, into an electrical signal, and records the converted electrical signal. Thus, the disdrometer system has an effect that the shape, volume, number, falling velocity of precipitation drops, and the intensity, density and weight of rainfall can be integrally measured.
