Laser Imaging

Laser Imaging is a powerful tool for Multi-Parameter Flow Imaging.
LaVision combines, in a unique way, flow velocity imaging based on Particle Image Velocimetry (PIV) with imaging of scalar flow parameters such as concentration, mixture fraction, and temperature applying Laser Induced Fluorescence (LIF), Raman and Rayleigh techniques. High resolution droplet sizing and particle imaging are accomplished using Interferometric Mie Imaging (IMI) and shadowgraphic imaging, respectively. In addition, particle concentration fields are recorded using Mie scattering or Laser Induced Incandescence (LII). Laser Imaging builds up a complete framework of seven imaging techniques with complementary information about the flow field (see Multi-Parameter Laser Imaging Matrix).

Combination of techniques captures additional flow features like:
Heat Transfer
Mass Flux
Global Droplet Size
Simultaneous imaging allows instantaneous multi-parameter flow field visualization and quantification.
