High Speed Camera Vision Inspection @ 1000 frames/sec or 500 frames/sec

High speed grey scale progressive scan monochrome imaging at 1000 frames per second and advance computing software facilitates fast mathematical algorithm compilation of DV01, DV09 and Sauter Mean Dv32 droplets. Large quantitative number of droplets, surface area of droplets and volume of droplets can be accurately determnined.

With EVolume / ESurface Area, you get DV32 sauter mean of a spray trajectory at a set pressure. Besides capturing the spray angle, the spray droplets velocity on exit can be accurately ascertained.

With the constant advancement of computing speed and memory storage capacity, Big data can be complied and spray test characteristics gathered effortlessly. Gone are the days of archaic phase doppler technique
