Zusammenfassung:The invention relates to a device for characterising the size and/or the shape of hydrometeors, comprising: a single camera (6), and a screen (8); a first radiation source (2) and a second radiation source (4), the angle of emission of each of said sources being wide, such that it is greater than 50°; and electronic processing means (16, 17) which are programmed to treat the data of at least one image of hydrometeors and/or the shadows thereof displayed by the camera, and to estimate at least the size and/or the shape of the hydrometeors.
