IDM: Inkjet Droplet Measurement
Droplet size and velocity spray distribution measurements
Droplet size versus time, 40 drops generated, 40 drops measured.
Droplet velocity versus time for a single injector scan generating 40 drops.
Droplet size and velocity distributions. Drop size standard deviation to less than 0.05 μm.
Two components of droplet velocity measured with stability to 3 to 4 mm/s and a resolution of 0.1 mm/s.
