The Spray Geometry system is used for characterizing spray shape and quality.
It consists of an illumination system, a camera and DynamicStudio software for image acquisition and analysis.
Either background illumination for shadowgraphy, or light sheet illumination for Mie scattering or Laser Induced Fluorescence (LIF) can be used.
For fast pulsed sprays such as fuel sprays, a laser light source is recommended for its short and intense light pulse.
