VisiSize D30 Shadowgraph system
VisiSize D30 Shadowgraph system - an Oxford Laser manufactured instrument, originally designed to characterize sprays via shadowgraphy imaging, was applied for the first time to the Atmospheric Science by Cloud dynamics and atmospheric turbulence group at IGF-UW. The VisiSize D30 is utilized to measure the size distribution and number concentration of cloud droplets and precipitation particles.
