SprayWatch-2i System Manufacturer: Oseir Ltd. [ Website: http://www.oseir.com/docs/templates/basic_2.php3?page_id=49 ] The system is able to measure real physical parameters of the spray such as: particle temperature velocity flux and distribution spray width angle position intensity Process The image processing algorithm measures the particle traces on the CCD detector Images the particle flow and measures the important characteristics of the particles just before they form the coating on the target surface The developed software algorithm identifies individual particles in the images and measures their position, direction and velocity.
