We present a novel polarization based metrological method of 3D shape measurement for in-line control of optical surfaces and control of highly aspheric optical surfaces. This technique is fast, non contact, high resolution, alignment free and with unprecedented dynamic. It has the potential to reach tens of nanometers accuracy. In this paper we show that a polarization imaging camera combined ...

A simple theoretical formalism is developed to describe the effect of transmission on linearly polarized light through a fiber with random fluctuations of birefringence. We conclude that, for any optical fiber that does not experience polarization-dependent gain or loss, there exist two orientations for linearly polarized light input into the optical fiber that will also exit the fiber linearly...

The optical absorption anisotropy of multi-walled carbon nanotubes (MWCNTs) has been quantitatively characterized through the determination of the absorbance and the degree of linear polarization. A model considering the orientation of the MWCNTs and the sensitivity to both co-polarized and cross-polarized radiation, through electric field depolarization effects, was used to understand the expe...

We have fabricated hybrid magnetic complexes from V atoms and tetracyanoethylene ligands via atomic manipulation with a cryogenic scanning tunneling microscope. Using tunneling spectroscopy we observe spin-polarized molecular orbitals as well as Kondo behavior. For complexes having two V atoms, the Kondo behavior can be quenched for different molecular arrangements, even as the spin-polarized o...
