This blog does not allow to upload large video clips and we now use the service of Google video to show you some of the experimental set-ups, systems and measurements we’ve done.
The first in the line is our invention, XPIV - mutliplane stereoscopic particle image velocimetry system. As you will see in a minute, it is very simple, easily extendable from your standard stereoscopic PIV system and the only missing ingredients are a) high-energy cubic beamsplitters, b) rotational mount with a half-wave plate, c) some sophisticated image processing and d) know-how. The last two components are kept with us, but we’re open for cooperation and look for the new challenges. The rest costs less than 1000 USD and it’s all on-shelf products. Highly recommended.

[...] In addition to the XPIV video clip we uploaded some old animation that was found on one of the NASA sites but unfortunately disappeared from the web. We use it in our courses and it’s very good animation, showing in quite comprehensive way the Particle Image Velocimetry principle. Enjoy. [...]
[...] Do you remember our XPIV? It’s a simple and reliable technique for the multi-plane stereoscopic PIV measurements. Three parallel laser sheets illuminate the flow field and a single pair of PIV cameras acquire the image of the particles from all the three planes. Some image processing and that’s it. You can see the details here, the video is here and the publication is in Experiments in Fluids, 2004. Why do I tell you this story again? It’s because accidently I found the following image from NASA. More precisely, it is used by MIT Courseware of the course of Compressible Fluid Dynamics, see here [...]
