Abstract:
We study the three-dimensional nature of a toroidal electrothermal microvortex (EMV) by using wavefront deformation particle tracking velocimetry (PTV) developed at the Universität der Bundeswehr München. A cylindrical lens is used in conjunction with a microscope objective lens to create systematic wavefront deformations in the particle images. The particles are observed by a single camera and appear as ellipses. The elliptical nature of the particle images encodes out-of-plane information rega...    »
