Particle Imaging Disdrometer
For droplet and particle size, morphology, velocity, and concentration

Measuring precipitation-simulated rain fields, snow fall, and hail are of significant importance in meteorology. Additionally, developers of hypersonic flight systems have urgent requirements for assessing the suitability of various aerospace materials that can withstand exposure to rain and other atmospheric conditions while these systems travel through the atmosphere. Under rain (or snow) conditions, there is a need to understand the reaction to the materials as a result of impacts with the mass, size, and quality of raindrops and how these impacts damage the vehicle materials.

​

Artium Technologies has developed Disdrometer Imaging Systems (DIS) to measure droplet and particle size, morphology, and concentration, as well as velocity using Particle Tracking Velocimetry (PTV). The Disdrometer is rugged and can withstand rough handling, shocks, and vibrations. Image illumination has enhanced uniformity and homogeneity which minimizes sensitivity of image processing methods to variations in background light intensity. The image capture area has a 2 to 1 aspect ratio with an overall field of view of approximately 140 x 70 mm (9,800 mm2) to maximize the data rate and limit window contamination.
