LaVision presents the latest innovation for stray light suppression in sprays and two-phase flows

Structured Laser Illumination Planar Imaging (SLIPI) is an established technique in planar laser imaging to remove imaging artifacts arising from higher order scattering in 2-phase fluids, such as sprays.

Developed from our cooperation partners from Lund University, LaVision now provides a remarkable simplification of
SLIPI with the new single pulse SLIPI approach.

Instantaneous 1p-SLIPI
This novel technique reveals fully time resolved spray images from single-shot recordings. Single pulse SLIPI (1p-SLIPI) is the simplest way of rejecting stray-light in dense media.

The instantaneous double pulse 2p-SLIPI and the phase-scanning and time-averaging 3p-SLIPI offer solutions to customers with higher demands on spatial resolution or for more complex spray imaging techniques like LIF/Mie.
The SLIPI optics is designed to start with the most simple 1p-SLIPI approach and can be upgraded with rising demands. The SLIPI base module covers all requirements for 1p-SLIPI. Two add-on modules for the SLIPI optics for 2p- and 3p-SLIPI allow to upgrade to one or both of the more advanced techniques.
