We're hearing more and more about Photonics. But what is Photonics? Since 2015 and the Year of Light, the term Photonics has taken a new turn with a democratization of the word to the general public. In this article, we'll explain how Photonics...
A rainbow is caused by the interaction of a beam of light with a drop of liquid. In the laboratory, rainbows formed by a laser beam illuminating a drop of liquid can be studied. By filming the rainbow, we can then study and extract physical information about the drop from this signal. In...
PIV (Particle Image Velocimetry) is a tomographic imaging technique. It measures the flow velocity of fluids seeded with particles (or "tracers"). These tracers must follow the movements (in space and time) of the fluid under study. They must also be in high concentration...
