[La Vision]


LaVision's ParticleMaster system family is designed to simultaneously determine size and velocity of individual particles or droplets in fluids or multiphase flows. The imaging systems analyze various types of particle laden fluids and other two-phase flows with high spatial resolution. Data acquisition and on-line evaluation are performed with the versatile DaVis software.

  • simultaneous size, velocity and position of individual particles
  • velocity-size correlations
  • morphology and shape information
  • mass flux and number density
  • ensemble statistics, frequency plots and histograms
  • visualization of ligament formation, spray break-up and atomization

Imaging Techniques
Shadowgraphy (backlight illumination)
Interferometric Mie Imaging (IMI)


  • integrated turnkey particle imaging systems matching optimal selection of illumination and detection devices
  • complete hardware control and timing with versatile DaVis software
  • accurate hardware and size calibration
