The visitor of the ISPIV2019 conference could convince themselves of the measurement options accessible with LaVision‘s LED-Flashlights 300 blue and white. Both are easy to set up and safe to operate. The new high-power blue LED is ideal for volumetric flow measurement with fluorescent tracers allowing suppression of background stray light with appropriate filters. In the live demonstration LaVision’s 3D camera MiniShaker recorded a 2-phase flow. LaVision thanks all visitors for their lively interest in our exhibits and in our talks about time-resolved and multi-pulse Shake-the-Box, Fine Scale Reconstruction and volumetric microscopic flow measurement by Tomographic PIV and Shake-the-Box. Our particular thanks go to the organizers for their commitment for a successful conference and for the open online access to the conference proceedings via the conference website
