3D Phase Imaging
26/07/2017, Filip Ligmajer
We are able to perform quantitative 3D phase imaging of plasmonic metasurfaces.
Using coherence-controlled holographic microscopy we can obtain information about the phase of light from the whole field of view of an optical microscope in a single measurement. We show that this technique can be used for performance assessment of phase-altering metasurfaces - a new class of artificial materials that allow to manipulate the wavefront of passing light and thus provide unprecedented functionalities in optics and nanophotonics.
