Digital holographic imaging for free surfaces of superfluid helium
Vitor S. Barroso, Patrik Å vanÄara, Chris Goodwin +9
Visualising the free surface of superfluid helium offers a rare opportunity to explore wave dynamics in the limit of vanishing viscosity. Such measurements are nonetheless challeng…

Optical lever for broadband detection of fluid interface fluctuations
Sreelekshmi C. Ajithkumar, Vitor S. Barroso, Patrik Å vanÄara +2
We exploit the optical lever principle to detect minute fluctuations of a liquid-air interface. Waves propagating on the interface deflect a specularly reflected laser beam, induci…
